Summer odds and ends - butterflies, shorebirding in Niagara, etc

It has been another busy summer for me. Unlike recent years where my work has brought me to a variety of locations in northern Ontario, this spring and summer I have been restricted to job sites throughout southern Ontario. While racking up the mileage cheques has been nice, I certainly miss the vast expanses of forests and the accompanying birds, herps, mammals and insects found throughout the boreal forest, especially since most of my job sites this year have been in less than pristine locations, often within cities or agricultural areas.

While I have observed a good variety of wildlife including a few new ode and lep species for me, I have often left my camera at home. That being said, I have photographed the odd thing here and there. Below are a couple of my better photos from the summer, though most of these are very common species. Often my "best" sightings have occurred during the middle of the day when the harsh lighting does not lend itself well to photography, or they have happened when I was without my camera (far too common of an occurrence, unfortunately). There are still a bunch of photos I need to edit from the last month - these are just the ones I have looked at recently.

In October of last year I moved to Niagara-on-the-Lake from Aurora, a location which had been my home for over two years. Since arriving in Niagara I have been working on building my Niagara Region bird list, though that took a bit of a hiatus over the winter since I was rarely in the province. But I have tried to ramp it up in recent months. The month of May is always the busiest for a birder and like usual I devoted most of my time to birding in one of the province's hotspots - Point Pelee. However I still managed to check some local spots in St Catharines here and there and slowly added new Niagara "ticks", most of them being relatively common migrants such as Solitary Sandpiper, Rusty Blackbird, Common Nighthawk and a variety of warblers such as Northern Parula, Blackburnian, Pine and Cape May. I did not find any notable rarities in Niagara this spring, however I was content to bird some of the local hotspots and slowly come across some relatively common species that I was missing for the county. Finding a Fish Crow at Port Weller was certainly a highlight, and given other sightings from the usually inaccessible west pier, it is a species that just may be breeding here.

As spring morphed into summer I have been focused on finding breeding birds, hoping to fill in some of the gaping holes in my list. I have been somewhat successful in that regard, adding Hooded Warbler, Pileated Woodpecker, Common Gallinule, American Woodcock, Black-billed Cuckoo, Eastern Whip-poor-will and Marsh Wren.

Now that we are in mid-summer my focus has shifted to one of my favorite groups of birds - shorebirds. Here in Niagara we are not blessed with an abundance of good locations to find this group of highly migratory birds, and as I am located in Niagara-on-the-Lake it is nearly an hour drive to access the Lake Erie shoreline which is often the best location to find shorebirds. This year has also been a bit of a down year as the water levels of Lake Erie seem unusually high, hiding much of the available shoreline habitat.

However, the dry weather we are currently experiencing is beneficial in lowering water levels at a few select places, including the Avondale Ponds near Niagara-on-the-Lake and Mud Lake Conservation Area near Port Colborne. While action at Avondale has been pretty slow and the location does not provide a ton of habitat, I was pleased to encounter an adult Baird's Sandpiper there the other day - the first Baird's to be reported in Ontario so far this year. As I was without my camera these digiscoped photos will have to do.

Mud Lake CA has become a favorite of mine to check in the last week or so. It is only a half hour from my office, and on recent visits I have been surprised to encounter quite a few shorebirds here, a location  that is usually devoid of those species in typical years. Mudflats have appeared this year, and of course shorebirds and herons have dropped in to take advantage of the feeding opportunities. Along with over a dozen Great Blue Herons, up to 35 Great Egrets have been seen here in recent days, picking off the numerous frogs and small fish that have congregated in the shallows. I would not be surprised if a rare heron drops in eventually - the question is whether it will hang around long enough to be found! I would be happy with Tricolored Heron, Little Blue Heron, or White-faced Ibis, though I certainly wouldn't turn down a Glossy Ibis or Snowy Egret....heck even whistling-ducks should be looked for since Black-bellied Whistling-Ducks seem to be on the move during this dry summer.

Several new additions to my Niagara list have occurred here recently including Sora, Virginia Rail and Least Bittern. Of course Mud Lake was also the location where Blayne and Jean Farnan discovered the Mississippi Kite back in May that hung around long enough to delight many birders.

Two days ago I encountered an adult Stilt Sandpiper that was mostly in breeding plumage at the site - a big highlight for me since Stilt Sandpiper is one of my favorite shorebird species. I am not sure why it is a favorite - perhaps because it has a very distinctive posture and feeding technique visible from a great distance, or because it has a very distinctive breeding plumage that isn't seen in its entirety too often in Ontario, or because it is a somewhat rare migrant in the province that is often only seen during autumn migration. My apologies for the quality of the photo - it was taken with my phone through my scope zoomed in at 60x from a decent distance. It can be aged as an adult bird (as expected this time of year - juvenile Stilt Sandpipers usually appear in September) as it is retaining much of its breeding plumage, including barring on its underparts and an orange cheek patch. While some of our shorebird species begin molting once arriving on a majority staging area or their wintering grounds (i.e. Short-billed Dowitcher), others including Stilt Sandpiper actively molt during their migration through Ontario. Often, new individuals can be identified at a location by comparing their degree of molt.

Other shorebirds at Mud Lake in recent days include Semipalmated Plover, Pectoral Sandpiper, Least Sandpiper, Semipalmated Sandpiper, Solitary Sandpiper (including a high count of 18 recently) and Greater Yellowlegs among the numerous Lesser Yellowlegs, Killdeer and Spotted Sandpipers. The diversity and numbers change frequently and this location should be checked daily. It is only a matter of time before a Ruff or something even rarer decides to drop in. The nice thing about Mud Lake is that it provides so much suitable habitat that a wayward shorebird may be enticed to hang around for a few days or weeks. If we continue to have a dry summer and the water levels at the lake remain low it will be an excellent birding location throughout the autumn - I know I will be checking it every couple of days from here on out.

Coming soon?

Sounds good to me!
