Title: Warblers + Sandpiper
Post by: nkwali on September 05, 2017, 04:16:41 PM
Ah, the joys of fall warbler identification. I'm looking for confirmation or correction on id's on a couple of warblers and a sandpiper.

Thank you

Blackburnian Warbler

i know eh , nkwali

i was up at Mara Provincial Park, Orillia this past weekend, and i found that the Peterson Guide was great for Confusing Fall Warblers....

it really helped me with the magnolia warbler -- "White band at midtail" -- which i did clearly observe.

Thanks Reuven & MC

I assume Blackpoll because of the streaking on the chest? Or are there other differentiating features?

***EDIT*** The eye-arcs on this bird do not eliminate Blackburnian so please ignore my comment below.  

The top bird is a juvenile Yellow-rumped Warbler, not a Blackburnian.  The well-defined eye arcs eliminate Blackburnian.  The bill is also on the large side, and for juvenile Blackburnians would be two-toned - black and pink.

Cheers,
Iain

Looking again it's not a Blackburnian or Yellow-rumped, but a young Pine. Compare this image: https://www.allaboutbirds.org/guide/PHO ... rnholt.jpg (https://www.allaboutbirds.org/guide/PHOTO/LARGE/piwa_dawnvornholt.jpg)
The placement of the yellow and the face pattern aren't quite right for Yellow-rumped.

I've received a couple of additional opinions on this bird from two more expert Toronto Birders and neither of them came back with Yellow-rumped or Pine.  One thought Blackburnian and the other thought Cape May - reasoning below.  As Reuven pointed out, the yellow wash on this bird's breast is not right for Yellow-rumped (neither are the light coloured feet) so I apologize for the incorrect ID.

Here are the cases for each species from the other two birders I heard from:

Blackburnian - Streaking, yellowish breast, wide supercilium and triangular face patch
Cape May - Short, pointed bill, shortish pale supercilium, yellowish flush behind the ear-coverts and on the breast.  Crisp dusky streaking along the breast sides and flanks and the bold white wing bars.

So we are undoubtedly dealing with a 'confusing fall warbler'.  I will likely post this bird to a Facebook bird ID group to see if we can get a consensus and will post the findings here.

If these help - here are two more photos of the same warbler. They aren't the greatest - but perhaps will provide some additional clues.
Much appreciate all the insights.

Thanks for posting more photos Nkwali.  Have passed them along and will let you know what we get back.

I vote for Blackburnian with the strong supercilium and wing bars.
