My First Fall Warblers - 23 Aug 2023

With rain forecasted this evening I took the opportunity to go to Elizabeth Park to look for warblers. The first warblers were reported there a few days ago, and even a Connecticut Warbler was found.

I arrived just before 9 am and headed to the interior portion of the park. The trails were quiet with birds neither being seen nor heard. That changed when I saw a nice flock of birds actively foraging and chasing each other next to the maintenance yard. The first birds were Black-capped Chickadees, but then several "Baypolls" were seen; Bay-breasted Warblers and/or Blackpoll Warblers. I reached for the camera and started approaching hoping to get some images in the relatively low-light of the forest understory.

Several Black-and-White Warblers were foraging, and they provided the first images. At shutter speeds of 1/200 sec. to 1/400 sec. I had a hard time getting sharp images at my effective focal length of 1260 mm. 







A Tennessee Warbler was a nice find (thanks to Daryl Bernard for the ID help).



The best way to separate Blackpoll Warblers from Bay-breasted Warblers in the fall is to look for feet color: orange on Blackpoll Warblers and black on Bay-breasted Warblers. This Bay-breasted Warbler has black feet but also shows the olive-green back and head of its confusing cousin.


This Blackpoll Warbler is showing orange feet.



I was pleasantly surprised to see several Blackburnian Warblers working the low branches. The triangular-shaped cheek patch is the best clue for ID'ing these birds. This one has a strong yellow-orange wash that also helped.


While chasing the fast-moving flock along the edge of the maintenance yard this Ruby-throated Hummingbird flew in and perched nearby. As it turned its head a single ruby gorget feather appeared that ages this bird as a first year male.






Another Black-and-White Warbler appeared.




A Black-throated Green Warbler appeared. Very similar-looking to the Blackburnian Warbler but its throat was white and the cheek patch is not triangular in shape.



A preening American Redstart.




Yet another Black-and-White Warbler.






A Least Flycatcher flew in and perched nearby. That bright eye-ring helped w/ the ID.







This bright Blackburnian Warbler popped into view and began foraging near the ground.
















Bay-breasted Warbler (note black feet).






Another Blackburnian Warbler.



As quickly as they appeared the flock moved off. I walked around and made another loop of the area but could not find anymore birds. So, I decided to run over to Lake Erie Metropark and walk the Marshland Museum nature trail.

Things were fairly quiet until I came upon a Yellow-bellied Flycatcher along the east trail near the Eagle Overlook. Lighting was not good, but I managed a few keepers.




Along the west side of the trail I came upon a small flock of Blue-gray Gnatcatchers and Magnolia Warblers. The gnatcatchers were moving close by until a Ruby-throated Hummingbird flew in and chased them off. The pair of Magnolia Warblers were foraging closer to the ground, so I focused (or tried) on them.











Despite the poor lighting I was very happy with my first warbler outing of the fall.
