Early spring exploration in Niagara

April is one of my favourite months of the year. After a long Canadian winter (relatively speaking, given my location in the "banana belt of Ontario"), the month of March arrives, usually more frustrating than hopeful as winter and spring trade blows. But usually by early April spring seems to have arrived for good, and any lingering bouts of winter are short-lived. New migrant bird species begin arriving daily, wildflowers emerge, first on the south facing slopes but soon they carpet the entire floor of woodlands, and the trills and peeps of Western Chorus Frogs and Spring Peepers reverberate from their ephemeral wetland habitats. With so much life all happening at once I try to spend as much of the month of April outside as I can.

Over the last few weeks I have explored several areas, all relatively close to home here in Niagara Region. My favourite location to visit during the spring is the Port Weller east pier. This vegetated, man made peninsula is an excellent location to see a variety of birds. As I have detailed in the past, Port Weller also functions as an excellent "vagrant trap" due to its geography (I'm talking about birds, not people). Port Weller has a long history of rare birds, including the likes of Ancient Murrelet, Dovekie, Tricolored Heron, Ross's Gulls, Mew Gull, California Gull, Tufted Duck, Sage Thrasher, Western Kingbird, Rock Wren, Great Cormorant, Northern Gannet, Purple Gallinule, Bell's Vireo and Lark Sparrow.

My first spring visit to Port Weller this year was on April 8. The sun was shining, the chorus frogs were singing and a nice variety of birds were present up and down the pier. I was happy to see my first Fox Sparrows of the year, though as is typical with this species they were not too cooperative for photos.

A few Yellow-bellied Sapsuckers were in as well. They seem to move through quickly here in Niagara and it is not hard to completely miss the species during spring migration!

But the day really belonged to Eastern Phoebes. While Port Weller is a fantastic vagrant trap, it is rare to see high numbers of migrant songbirds out on the pier. The nine Eastern Phoebes on this day was by far the most I had ever seen out there. Most of them were along the sheltered east side of the pier.

Ducks are a big feature of any birding at Port Weller from August through April. The mix right now is pretty typical of western Lake Ontario - lots of Red-breasted Mergansers, Common Goldeneyes, Buffleheads and Long-tailed Ducks, with a smattering of other species mixed in. The dabbling duck scene changes daily but often includes Blue-winged Teal, Northern Shoveler, American Wigeon, Gadwall and sometimes Wood Duck. The Long-tailed Ducks in particular are an enjoyable study in April, as they make the surprising transformation from their paler winter plumages to their striking breeding plumages. Soon, these Long-tailed Ducks will be back in the Arctic wetlands that are their home for a few short months.

White-winged Scoters are the only regular scoter at Port Weller and most sightings are of individuals way offshore. This one next to the pier was a treat to watch.

As I continued north up the pier, the calls of Western Chorus Frogs emanating from the small pond were just deafening! It was pandemonium, and I could hardly hear myself think due to the volume. I went into "stealth mode" and ten minutes later had a male teed up for photos. Western Chorus Frogs can be really hard to actually see, and these were the first ones I had a chance to photograph in a half dozen years at least!

It is amazing how many of these Western Chorus Frogs congregate in April in this wetland, when I have never once seen one at any other time of the year at Port Weller.

Strong, south winds can make the visible raptor migration at the south end of the pier quite excellent. Recently, the theme has been Sharp-shinned Hawks, Turkey Vultures and Red-tailed Hawks, but I have seen a few other species mixed in here and there including Merlin, American Kestrel and Northern Harrier.

On April 12 I returned to the pier for another walk. It is always an exciting location to visit during the spring as the mix of birds changes daily. Songbird numbers were a bit lower on this date, but new arrivals included Eastern Towhee, lots of kinglets and a flock of Brown Creepers.

Larids stole the show on this date, however. An Iceland Gull was flying around with the Herring Gulls, Caspian Terns were in, a surprise Forster's Tern appeared (they are perhaps annual at Port Weller, usually in mid-April), and a Little Gull was doing laps with Bonaparte's Gulls at the end of the pier.  Bonaparte's Gull numbers are steady in mid-April as they migrate through and I was hoping to eventually get a Little Gull with them.

April 13 was another great day at Port Weller, with a new mix of birds once again. Highlights on this date were my first Fish Crows of the spring (finally!), an early House Wren, a Glaucous Gull and a nice variety of migrating raptors. Speaking of Fish Crows, they are back in my neighbourhood, showing up right on time (it is usually mid to late April when they become regular here). A pair of Merlins have been checking out some old nests in the area, and being very vocal. Fingers crossed that they stick around!

Last weekend I went for a walk-around at Wainfleet Bog with Laura as well as our friends Dan and Nikki who were visiting for the weekend. A fair bit of bush-whacking was required to access some of the areas due to high water levels, but we managed! The Eastern Gartersnake at Wainfleet have a unique colouration, likely caused from staining due to the tannins in the bog.

We discovered our first Northern Redbelly Snake of the year as well! This species comes in both brown and slate-gray colour morphs. I seem to see the brown morph maybe 2/3 of the time in my travels.

Tick checks are mandatory following any of our visits to Wainfleet, for good reason...

Easily the biggest surprise during our visit to Wainfleet was this flock of eight Sandhill Cranes that flew in, circled around, and continued west. Sandhill Cranes have bred in the area in the past, though its status in Niagara is still relatively unknown. I am usually lucky to have two or three sightings a year in Niagara, and I've never seen eight at once before!

Rusty Blackbird was formerly an abundant species but the global population has crashed in the last few decades to just a shadow of what it formerly was. For me, sightings of this enigmatic species in Niagara are cause for celebration. There is something about hearing their distinctive gurgle song that puts a smile on my face! A quartet of Rusties were hanging around in one of the flooded swamps at Wainfleet.

The next post will include more sightings from Port Weller as well as from Morgan's Point near Port Colborne.

January 25, 2019


The rollicking squawks of White-bellied Chachalacas provided a natural alarm clock, signalling the beginning of a new day. Dan and I were excited to have the full day at our disposal, with no time wasted driving to a new location. 

As dawn broke we stationed ourselves near the base of a large flowering tree that had attracted a number of birds. Among the various tanagers, orioles and parakeets were a few new ones for us - Spot-breasted Oriole and Scrub Euphonia.

We watched for other species for a while, turning up a few new hummingbird species (Blue-throated Goldentail, Blue-tailed Hummingbird) followed by a hearty breakfast at the main lodge. After wolfing down our food we traced our steps back to where we had hiked during the previous evening, into the forest located down the road from the main lodge buildings. One of the trails encircles a small valley, with enough openings in the vegetation to provide excellent near-eye-level views of many species. A nice selection of birds were found while the hot morning sun was also good for butterflies and lizards.

This is Dasymutilla munifica, a species of Velvet Ant that Dan spotted on the trail. The wingless females of this wasp species resemble large, gaudy ants. Velvet Ants are known for their extremely painful stings and are sometimes referred to as cow killers for that reason.

Among the new birds on our morning walk were our first Northern Bentbills of the trip, as well as a few lekking Long-tailed Manakins. On the way back we spotted a locally rare White-necked Jacobin, capping off an excellent morning of exploration.

Some readers may be surprised to hear that White-tailed Deer are in fact quite common throughout Central America, ranging south all the way to Peru. The ones at Los Tarrales are quite tame.

Dan and I had been going pretty hard for the first week of the trip and the five hours of sleep a night was starting to catch up to us. As the lodge at Los Tarrales is located at only 750 masl the temperatures become quite warm during the middle of the day. We decided to (mostly) take it easy for a few hours during the heat of the day, exploring a few areas close to the lodge. New for me were a couple of species that Dan had seen before - Berylline Hummingbird and Spot-breasted Wren. We tried playing the tape again for Rufous-breasted Spinetail but had to settle for only hearing the bird respond once.

A bunch of bananas had been strung up outside of the main lodge building and at various times of day different species could be seen here. I took a few moments to photograph some of the Yellow-winged Tanagers who frequented the banana bonanza.

By 3 PM the bird activity had begun to pick up a bit. Dan and I hopped in the pickup truck and headed up a dirt road that led away from the lodge and up the side of the volcano. Perhaps 10 km up this road is a little settlement called Vesubio, home to a few families that farm coffee beans in the area. Vesubio is also one of the most reliable places in the world to search for the range-restricted Azure-rumped Tanager, one of our main bird targets of the trip. We had planned on driving up there the following morning anyways, but decided to scout it out ahead of time during the daylight, given how rough the road was.

This turned out to be a wise decision and we needed every inch of clearance that the Toyota Hilux provided. We inched our way up the side of the mountain, eventually reaching the community. We parked the truck and introduced ourselves to one of the guys that came over to say hi, then strolled around while listening for the high pitched call notes of the tanager. Unfortunately we were not in luck, though a Greenish Elaenia and several Emerald-chinned Hummingbirds were new species for both of us.

That evening Dan and I set off on foot to a pond only a short walk from the lodge that we had checked several times already, though only in the daylight hours. While the pond was surrounded by bananas, bamboo, and other disturbed vegetation types, we were hoping that with a little luck we could turn up some snakes.

The eyeshine of this Common Opossum lit up in my headlamp's beam during our walk over to the pond.

We circled the pond but despite lots of anuran life, snakes remained out of sight. Most numerous were the Giant Toads; true to their name, several were quite large indeed!

We also noted more Craugastor loki and Lithobates maculatus, two species that seemed to be common in the disturbed environments.

This frog was also numerous, though I haven't been able to figure out what species it is.

By poking around some discarded boards we uncovered a few more goodies: a Red Forest Skink, Smith's Tropical Night Lizard and Slender Brown Scorpion.

The genus Centruroides is notorious for having very toxic venom. This species (Centruroides tapachulaensis) is not known to be as dangerous as many of its relatives, though Dan and I decided not to risk it and left it alone.

Dan and I headed downhill to a nearby stream, hoping that the water would concentrate snakes. Almost immediately he shouted "Fer-de-Lance!". It was a hefty individual, perhaps five feet in length, which definitely got the blood pumping! Unfortunately the snake did not stick around for long as its hiding spot had been compromised, and it soon slithered off into a crevice underneath the bank.

The creek was difficult to follow so we returned to the crude trail that ran roughly parallel to it. A few minutes later I was thrilled to spot a beautiful Mexican Mouse Opossum only a meter or two away, at eye-level in some bamboo. Awesome!!

Dan and I were pretty excited as this was the first mouse opossum that either of us had seen. These marsupials are as tiny as a mouse, and impossibly cute!

One more snake was in store before we called it a night. My headlamp beam picked up the distinctive banding of another Blunthead Tree Snake, this time an adult, in some waist-level vegetation. We were a bit desensitized to this species after the numerous sightings during the previous evening, but duly photographed the beaut anyways. I love the big bulging eyes and calm disposition of this species.
