Recent news (or lack thereof)

Yeah, I haven't updated the blog with epic bird sightings over the past week. But there is a good reason for that! Mainly because I have not had any epic bird sightings lately.

Ever since being back at school, I have been quite busy and haven't really been out much. Some of this is schoolwork, but mostly it is socializing since that didn't happen a whole lot this summer. I had grand plans this weekend to do some birding, but yesterday and today left me nursing a hangover instead. Oh well.

I did actually get out for a bit yesterday afternoon and headed over to Guelph Lake in the north part of town. This man-made lake is a favorite local spot of mine and the site where Dan Riley and I had a Parasitic Jaeger (first Wellington Co. record I think?) on October 22, 2010. Unfortunately it was very quiet there today. Water levels were way down leaving quite a lot of mudflats, however only Killdeer and a single Spotted Sandpiper were present. A few ducks included an American Wigeon and some Green-winged Teal. Various songbirds were flitting around the edges, but nothing noteworthy.
I then checked out the ponds along York Road east of downtown, and was surprised to see several hundred geese hanging out. They seemed to be mostly the interior subspecies, and with them were 6 spanking Cackling Geese. The cacklers were hanging out in a type group off to the edge of the flock.

Here are a few photos I took at the OFO conference a few weekends back that I finally got around to editing.

In other news....
It is now October, which means it is prime rarity finding time! Once this weather system finally passes to the east and more birders get out with the fine weather forecasted, I wouldn't be surprised if a few good birds turn up.
The season is definitely heating up and there have been some decent sightings lately.

- Holiday Beach had its second Swainson's Hawk of the season yesterday, a dark-morph adult. Jealous...

- at least 2 Lark Sparrows have been found in the province, and there could definitely be more!

- an American Avocet made an appearance at Rondeau yesterday (J. Burk) and there was a flock reported from Port Burwell as well (J. Stephenson et. al)

- a female Common Eider was reported from Grafton (between Cobourg and Presquille) and is still being seen (M. Bain)

Also, check out these photos of a Franklin's and Black-headed Gull from across the pond in Ohio. Taken by Geoff Malosh. This location also had 4 American Avocets. Why is it that some of these places along the lake get avocets just about every day, and on our side they are relatively rare?

That's all for now.

OFO convention at Pelee

Last night I returned from the OFO convention held at Point Pelee. Despite the low number of migrants in the park, I would still say the weekend was a success! It was great to meet old friends and to put some faces to names.

Saturday morning I drove from where I was staying in Windsor to Point Pelee. Steve Pike and I were scheduled to be a leading a hike throughout the onion fields and Hillman marsh in the morning. When I arrived Steve was already there, and he looked like death warmed over. He bowed out of the morning session and was hoping to be fine by afternoon, or at the latest, by the time of the dinner.

Our group first checked out the dyke that leads east towards the lake from the far end of concession road E. Despite relatively high winds we found a few pockets of songbirds, highlighted by Philadelphia Vireo and 10 species of warblers. A Wilson's Snipe flew by and some Harriers were seen flying around the marsh.

We made our way up to Wheatley harbour, which I had scouted the night before. Unfortunately both Lesser Black-backed Gulls weren't present, but 2 juvenile Ruddy Turnstones were.

After some discussion, our group decided to head north to a field near Wheatley which held American Golden-Plovers the day before. This turned out to be a very good move as not only did we have good looks at the Golden-plovers, but 5 Buff-breasted Sandpipers flew in to close range for a few minutes! The rest of the time, they were barely visible out in the fields. Also seen here were a few Black-bellied Plovers, Killdeer, Pectoral Sandpipers, and singles of Baird's Sandpiper and Lesser Yellowlegs.

Buoyed on by our success, we headed to Tilbury since it was close. The usuals were here, highlighted by a flock of 11 White-rumped Sandpipers. It was good to see birds actually using the "shorebird cell", now that it had a bit of water again.

The afternoon consisted of leading a convoy of over 30 cars back to the BBSA field. Fortunately for all the participants, we managed to see all 5 way off in the distance. Few other decent birds were seen that day, and I finished birding around 4:00 with close to 80 species for the day. Not bad considering I didn't even step inside the National Park!

I slept in my car Saturday night and decided to sleep in til about 8. I birded the park briefly, but it was very quiet for songbirds and I didn't see much. Highlights included Grey-cheeked Thrush and Mourning Warbler.
I did stop to photograph what I was told was a Variagated Meadowhawk.

On the way back home, I stopped at Tilbury but few new birds had arrived. The WRSA flock now numbered 14.

Photos to be added later!

More phalarope awesomeness

I decided to once again make the short trek over to Tilbury this afternoon while taking a break from work. Many of the same ducks and herons were still present, including the female Northern Shoveler (she was joined by 5 others on Saturday, but they were now gone), a handful of teal, a couple of Black Ducks, and a dozen Wood Ducks. While scanning the shorebirds, I was happy to see that the young Red-necked Phalarope had returned. It had been absent yesterday, apparently.

This is an awesome little bird and one of my favorite species. The lighting wasn't ideal at this time of day, but even still I slowly crawled down the embankment and grabbed about 100 photos of the little guy. Makes me wish I had an extra 100 or 200 mm on my lens!

Every so often, the phalarope would spin quickly in a circle, creating a vortex that sucks tiny invertebrates up to the surface, which it promptly plucked off of the water.

juvenile Red-necked Phalarope - Tilbury lagoons

About a dozen total species of shorebirds were present including 4 juvenile Baird's Sandpipers, an adult White-rumped Sandpiper (the first of the fall for me at Tilbury), and 3 adult Long-billed Dowitchers.

adult Long-billed Dowitcher - Tilbury lagoons

While I was watching the shorebirds, I noticed that they all started lifting a wary eye to the sky. I took this as a hint and looked up, but the only raptorish shape I could see was a Chimney Swift way up high. About 10 minutes later the same thing took place.

This time, though, the culprit was a juvenile Peregrine barelling in. It chased a flock of peeps around for a bit before eventually leaving. At one point the falcon was dangerously close to the phalarope, huddling close to the water! I found it interesting that the dowitchers and Greater Yellowlegs didn't fly when the Peregrine flew in - in fact the dowitchers never stopped feeding the entire time the aerial assault was on.

Peregrine Falcon - Tilbury lagoons

The flocks dissappeared, but over the next 20 minutes slowly started arriving and feeding. Here is a Lesser Yellowlegs trailed by a couple of peeps. I think the front two are Semi-sands and the back one is a Least.

Also seen was a single American Pipit, my first of the fall and first for Tilbury. I also heard a couple of Bobolinks as they migrated south over the lagoons (also new for my Tilbury list). I think I've seen close to 100 species of birds there over the last year.

Finally! A change at Tilbury

This morning when I posted I lamented how, despite excellent conditions, the rare birds were just not showing up at the Tilbury lagoons. I did have an American Avocet there early in July, but ever since then the rarest birds have been the regular Long-billed Dowitchers.

It seems that for today at least, the curse was slightly broken. While no rarities were found, there was a huge change in the numbers and diversity at Tilbury with a few interesting birds mixed in. Beforehand, let me mention that the quality of the photos leave something to desire. The birds were a little too far away for me to use the 300mm, so I resorted to digiscoping with my 18-55 lens.

My coworker, Matt, and I took a break from work and made the quick trip over to the lagoons. One of the first birds we saw was this Horned Grebe, hanging out with a couple of Pied-billed Grebes. What a weird sighting! I have never seen one at the lagoons. It almost seems that an Eared Grebe would have been more likely.

Horned Grebe - Tilbury lagoons

Around this time, another car pulled in and I realized it was my friends Ken and Mike Burrell. They were doing a big loop of the southern Ontario shorebird spots and had already seen an Upland Sandpiper at Mitchell and 2 Red-necked Phalaropes at Exeter. Together, the 4 of us scoped the "shorebird cell" at Tilbury with a few highlights.

This juvenile Red-necked Phalarope stood out and was one of the first birds I looked at. I nice surprise, and a new one for my Tilbury list (as well as Ontario year list, but who's counting).

Stilt Sandpipers had arrived. Earlier in the fall I had seen 1 or 2 adults, but today 3 juveniles were present. Neat looking birds, and one of my favorites.

I was happy to finally see a few Baird's Sandpipers at Tilbury - the first ones of the fall for me here. They were both juveniles.

Of course there were still Dowitchers - 3 adult Long-billed, and the rest juvenile and adult Short-billed. Some of the Long-billed Dowitchers were quite far along in their prebasic molt. No pics today.

Other birds seen include 14 Great Egrets (a lot less than the 40 Blake had!), 2 Black-crowned Night-herons, both species of Teal, 5 Northern Shovelers, and 8 Wood Ducks.

This afternoon I brought my camera into the field with me in case I came across any butterflies. I found a few Fiery Skippers and an un-IDed Duskywing. My guess is Wild Indigo.

I kind of like this shot of a Viceroy on the gravel path.

This mama and her two fauns kept an eye on me as I approached.

That's all for now. I am hoping to go to Pelee first thing tomorrow, or at the very least Tilbury again.

Not much news

Another week, come and gone. I did make it out to the Tilbury lagoons twice, and as expected, nothing new was seen.

Shorebirds included 11 species, and the highlight were the same 4 Long-billed Dowitchers. Many of them are undergoing extensive feather molt.

The duck scene is getting slightly more interesting. On Wednesday, among the 300 Mallards I noticed a female Bufflehead, 3 Northern Shoveler, 11 Wood Ducks, and a smattering of both species of teal. One can only hope for a Cinnamon Teal or Garganey.

At work, I spent an hour one afternoon with 3 of my co-workers as well as Tom Preney hiking through the Springgarden ANSI. We checked out a nice spot that had a large amount of Rough Blazingstar. Here is a Silver-spotted Skipper on it:

This appears to be a meadowhawk of some sort.

And finally, a little American toad I found sitting on a trail.

This weekend I am slated to work a fair bit but I am hoping to get out at least once to Point Pelee or Tilbury. I would also like to take a walk in the Ojibway Prairie and try to turn up some new butterflies.....

In other news...its almost jaeger time!!!! Once we get a few cold fronts followed by some east winds, Long-tailed and perhaps Parasitic should start to show up in western Lake Ontario. SW winds may bring something good to the tip of Pelee. Unfortunately I will miss the majority of Long-tailed Jaeger season because of my trip to Nova Scotia. It was not too long ago that a Manx Shearwater was spotted at Van Wagner's Beach early in the jaeger season (August 31, 2006), as well as a Long-billed Curlew (August 23, 2009).

Central Kingbirds and more

This past week I brought my camera into the field a couple of times and managed to get a few shots of some butterflies. Common Ringlets are becoming more and more common. I saw at least one every day last week!

Common Ringlet - Windsor, Ontario

Among the skippers seen last week was this Peck's.

Peck's Skipper - Windsor, Ontario

On Wednesday, I noticed an Ontbirds post from James Holdsworth about a Western Kingbird and 3 hybrid juvenile Eastern x Western Kingbirds. I have never seen hybrid kingbirds and the location was about 2 minutes from my office, so Dan Riley and I swung by one afternoon and took a look at these "Central" Kingbirds. Pretty cool to see Westerns attempt breeding in Windsor, even though only one half of the pair was the right species. The photos are pretty bad and I'll attribute that to the very poor lighting and heavy cropping.

The adult Western Kingbird was present too. I had only seen this species once before (an adult seen in November, 2009 in Port Burwell) so it was nice to reacquaint myself with the species. For better photos that were taken by James Holdsworth and Dwayne Murphy, check out Dwayne's blog: http://dwaynejava.blogspot.com/

Western Kingbird - Windsor, Ontario
Yesterday I decided to check out Point Pelee before going to Cambridge for the weekend. It was a beautiful day - warm but not hot, with a nice breeze coming in off the lake. Seacliff Beach was first on my agenda. I had a bit of fun taking some shots of the abundant Larids. There were 8 species of gulls/terns present - Caspian, Forster's, and Common Terns as well as Bonaparte's, Great Black-backed, Lesser Black-backed, Ring-billed, and Herring Gulls. The only LBBG was this individual, molting from 1st summer to 2nd winter plumage.

I had limited time in the park so I decided to walk the West Beach trail from the VC to the tip. Many Giant Swallowtails were taking advantage of the abundant Spotted Knapweed.

Giant Swallowtail - Point Pelee National Park

I was happy to see 2 new butterflies - 2 Dun Skippers (no photos) and 3 Horace's Duskywngs. Horace's had been reported on and off for the past week or two, but I was still surprised when I came across them.  They were all within 5 feet of the water's edge, landing on some of the vegetation that had washed up on shore.

This was an odd sight - a Great Blue Heron flocking with the gulls. Another 1st summer/2nd winter LBBG was with this flock as well.

A single Eastern Comma allowed me to take its photo.

From there, I headed over to the Tilbury lagoons. The conditions still remain excellent but still there wasn't much turnover. These lagoons are now probably being checked close to every day so I would imagine that if something really rare drops in, it has a good chance of being seen and reported.

Among the 12 species of shorebirds were 4 adult Long-billed Dowitchers, 3 Short-billed Dowitchers (including 2 juvies), and an adult Stilt Sandpiper. Only 3 Great Egrets this time.

A tour of Essex County

Today I decided to take full advantage of my day off and tour around, hopefully kicking up some cool birds and butterflies.
The first stop was Tilbury. This remains the best, easily excessible shorebird spot in the county and it wasn't bad today. There must have been a big influx of dowitchers as there were more than a dozen. 5 of them were Long-billed and a few juvenile Short-billed were around. I didn't get any photos as they were too far for my 300 lens. I did, however, grab a few shots of this closerish Lesser Yellowlegs.

Cormies!

Double-crested Cormorants - Tilbury lagoon

Next up was the Ridgetown Lagoons. I was actually disappointed as I thought that there would be more habitat than there was. The smaller cell did have mudflats, but the geese were hoarding them. There were, however, a handful of semi-sands, a single Least Sandpiper, a single Semi-Plover, and a couple Lesser Yellowlegs.

Blenheim was next on the agenda. I hadn't actually visited in a few weeks so I wasn't prepared for how terrible it would be. Every single one of the lagoons was filled to the brim with water, and even the sprinkler cells were completely dry! Highlights from here included Mallard and Starling. Well, there was still a single Semipalmated Sandpiper that I watched for a bit. I kind of felt sorry for it, "foraging" on bare dirt. I also scanned through about 500 Mourning Doves and didn't see anything interesting. On to Erieau!

Off the pier were various gulls and terns, including a 1st summer/2nd winter Lesser Black-backed. There were tons of people here hanging out on the pier, so I didn't linger. Off of Erie Beach I had a young Little Gull with the Bonaparte's, which I think is the first one of those for me this year.

Next I checked out Hillman Marsh, Wheatley Harbour, and the harbour by Sturgeon Woods. I didn't see anything unexpected, though I got a second Little Gull at the harbour by Sturgeon Woods.

The final stop was at a weedy field in Leamington to look for butterflies. 3 or 4 Common Checkered Skippers were nice!

Common Checkered-skipper - Leamington

As was this thing, which I think is a Fiery Skipper?

That's all for now. Overall it was a typical day for early August - hot weather, lots of driving, few birds, but a couple nice summering gulls/migrant shorebirds/southern butterflies.

This and that

Another week has come and gone with me unable to get out and go birding as often as I would like. I have been seeing a few things at work, including this Common Ringlet.

Common Ringlet - Windsor, Ontario

Common Ringlet has never been common in extreme southwestern Ontario, but it has been expanding as of late. The first Essex Co. record was only 10 years ago! This one location on my study site seems to be a hotspot for them - two days ago I had a high count of 6. I wouldn't be surprised if this is a record high count for Essex county?

Here is a neonate Butler's Gartersnake (regurgitating an earthworm) from the study site a few days ago. These guys have already tripled their weight since they were born (all my radio snakes gave birth between July 14 and July 27). They eat earthworms presumably every evening, and some then move under our coverboards to thermo-regulate and digest their meal.

Butler's Gartersnake - Windsor, Ontario

This 12-point buck is usually seen most days in one particular area of the study site. I happened to bring my camera with the new lens out in the field with me and got a few half decent shots in the fading light.

White-tailed Deer - Windsor, Ontario

Yesterday afternoon I heard from Russ Jones about a mysterious sighting of a possible Whooping Crane near the St. Joachim exit. I called Steve Pike and he mentioned that a friend of his who knows birds saw a "large white bird with black wingtips and a black face" fly over him while he was driving on the 401. This person saw the bird land in a field on the south side of the road. I guess another possibility is that this bird was a wood stork.

Dan Riley and I decided to check it out. We didn't find anything, so we continued on to check the Tilbury lagoons.

4 species of herons were present including 18 Great Egrets. This is the most that I have seen there this summer, and so I continue to hold out hope for a Cattle Egret, or maybe a Little Blue Heron! Reddish Egret would be nice too...

Great Egret - Tilbury Lagoons

This Black-crowned Night-Heron kept a watchful eye on me. It was one of five seen.

Black-crowned Night-Heron - Tilbury lagoons

There were decent numbers of shorebirds present of 10 species. The highlight were the dowitchers - 2 were definite Long-billed Dowitchers, and 2 were Short-billed. The two LBDOs were hanging out together up close, providing a great oppurtunity to study their plumage. The darker back, rounder body shape, more distinct lower half of eye-ring, and patterning on the undertail coverts/flanks were easy to see. 1 bird was most likely a female as it had an extremely long bill.

Thats all for now. I hope to do a round of shorebirding tomorrow, hitting up some of the hotspots in Essex/Chatham-Kent.

Birding around Essex

I met up with Ken Burrell and 3 of his coworkers - Megan, Nate, and Charlotte - for a day of birding/butterflying around Essex County. Bird-wise, it was pretty quiet: Some Moorhens and various wading birds at Holiday Beach (though no Cattle Egret), Sanderlings at the tip of Point Pelee, and the shorebirds at Tilbury were probably the highlight. Amongst the regular hoard of Spotted Sandpipers and Killdeer, we also picked out:
4 Stilt Sandpiper
4 Short-billed Dowitcher
1 Greater Yellowlegs
1 Solitary Sandpiper
40 Lesser Yellowlegs
40 Least Sandpiper
20 Semi-palmated Sandpiper

Butterflies were also in the news. At Pelee we saw many Giant Swallowtails, some Spicebush Swallowtails, Emperors (both Tawny and Hackberry), and an American Snout among others. My highlight was finding a worn Juniper Hairstreak right next to the trail on the west side of the tip. No photos, though Ken might have grabbed some on his camera.

Despite the lack of "good" birds, it was an enjoyable and relaxing day away from work!

Another day, another avocet

I almost canned my plans to check out some of the lagoons nearby after napping much longer than planned. In the end, I made the one hour drive to Blenheim, arriving with about an hour of light left. Due to my rushed schedule I didn't check out any of the lagoons and headed straight for the sprinkler system. The first bird that caught my eye was a huge shorebird with an upturned bill - an American Avocet. This avocet was much more advanced in its prebasic molt than the one I found at Tilbury, leading me to think that its a different individual.  I watched it in the scope for about a minute before the shorebirds got spooked by something and took off. Last I saw of the avocet, it was heading south. Unfortunately I didn't take any photos of this one because I left my camera in the car, and frankly, its a long walk back! Most of the shorebirds returned (minus the avocet), and they included:

30 Lesser Yellowlegs
20 Least Sandpipers
3 Solitary Sandpipers
1 Greater Yellowlegs
3 Pectoral Sandpipers
1 Semipalmated Sandpiper (first of fall for me)
X Killdeer, Spotted Sandpipers.

As I was scanning the birds I could hear two Dickcissels calling, one on either side of me. Sweet! It appears that the late spring/early summer droughts in the southern states may have pushed quite a few into southwestern Ontario.
Also, when I entered the avocet in the book at Blenheim, there was a mysterious sighting for an avocet on July 18 at noon. Is it a typo or is it a prediction?  Hmmm.....

I rushed over to Tilbury just before sunset to see what was around. And guess what I saw???

Not much, really. A few Black-crowned Night-Herons, a Short-billed Dowitcher, and a smattering of Least Sandpipers and Lesser Yellowlegs among the usuals. I had a female Hooded Merganser with the ducks, which is a new Tilbury bird for me. As night fell, ~10 Chimney Swifts were hawking insects with the swallows. The duck flock is now growing, with now over 100 mallards and a few other things mixed in. Last fall quite a few teal used this place, so I'm going to predict a Cinnamon Teal this fall!

Sunday, 10 July 2011

Tilbury tonight

On a whim I took advantage of the hour or two of light I had left this evening and drove down to Tilbury. Lots of birds were present, but only a few shorebirds. They were:
Killdeer - 40+
Spotted Sandpiper - 30+
Least Sandpiper - 9
Lesser Yellowlegs - 5
Pectoral Sandpiper - 2 (first of fall for me)
Solitary Sandpiper - 1

Also around were a few Great Egrets, 4 Caspian Terns, 2 Chimney Swifts (my first for Tilbury), Great Egrets, Black-crowned Night Herons, etc. Looks good for a rare heron soon! I checked the back of the lagoons and had many marsh wrens calling. No luck playing tapes for rails.

Check out this Black-crowned Night-Heron - a plumage I haven't really seen before. 1st summer or 2nd summer? Excuse the photo quality - digiscoping around sunset is not really a recipe for great photos...

Fall shorebird blitz - kicks off with a rarity

Shorebirds are probably my favorite group of birds for a few reasons. First, there is a wide variety of species that migrate through in large numbers. Second, many of the shorebirds can be difficult to identify, making it more of a challenge. And third, the chance of vagrancy is high with this group, making the search for rarities quite enticing.

Seeing as it is now early July, a few species are already on the move southbound. For the next few months, I am going to spend as much time as I can searching some of my favorite haunts for these migrants. Today was my first chance to go out and check my two regular spots that are relative close to where I work in Windsor - the Blenheim sewage lagoons, and the Tilbury lagoons.

After checking Hillman Marsh (it is pretty dead this time of year), I headed east to Blenheim, making a quick stop near Wheatley where a few Dickcissels have been hanging out for a while. Ken Burrell found a male here on June 16 and since then 2-3 males have been seen regularly. The birds did not disappoint and I had excellent scope views of one singing, with 2 others also singing off in the distance.

The Blenheim lagoons had a nice selection of early southbound migrants. Among 40+ Killdeer and 34 Spotted Sandpipers, I also found 2 Short-billed Dowitchers, 1 Greater Yellowlegs, 1 Solitary Sandpiper, 17 Lesser Yellowlegs, and 8 Least Sandpipers. They were all hanging out in the irrigation cells as the water levels were still quite high in all 5 lagoons. The back lagoon (number 5) also held a few families of Wood Ducks, a female Ringneck Duck, a male Green-winged Teal, some Ruddy Ducks, and 4 American Wigeons.

Tilbury was my next stop and it did not disappoint. I noticed a few ducks and shorebirds on a small exposed mudflat, and after looking with my scope, a nice American Avocet stood out. This is only my second sighting of this species in Ontario and my first for a few years. A few photos of the beast (please excuse the image quality - I was digiscoping with my 18-55 kit lens):

Also at Tilbury were 1 Black-crowned Night-heron (new for the year, surprisingly), 1 Great Egret, a few ducks of various species, 1 Lesser Yellowlegs, and about 10 Least Sandpipers.

So there you go. A nice start to the fall shorebird blitz! Last year I didn't get any rarities among the ~25 species of shorebirds I saw during the months of July, August, and September.
