Blackburnian Warbler (click to see the larger version)

Continuing the migration splendor for the week, Thursday, May 12 was the best warbler day of the spring at Montrose. I ended up with 26 species, which is about as good as we do. If you were at Montrose on that day you couldn’t help but be impressed with the volume and variety of warblers. My best finds include

Worm-eating Warbler
Black-throated Blue Warbler
Blue-winged Warbler
Golden-winged Warbler (3)
Northern Parula (3)
Mourning Warbler
Canada Warbler

Of the regularly occurring warblers, Worm-eating is the rarest and least expected. In addition, the large numbers of Magnolia, Chestnut-sided, and Blackburnian were a joy to look at. We wait all year for a handful of days with color like this. Link to my eBird checklist for the day below.
