FOS Summer Tanager and Blackburnian Warbler at Little Bear

 CAPTAIN SAMS

It was a very similar day compared to yesterday with some additional humidity. We captured 32 new birds and 8 recaptures of 15 species. The highlights of the morning were two species we do not catch often: Worm-eating Warbler and Wood Thrush. This was only the second captured of each species at the spit so far this season. Unfortunately, it looks like the heat is here to stay which may result in slow days through next week.

LITTLE BEAR
Little Bear once again surprised the crew by capturing more birds than Captain Sams with 50 total today. To no one's surprise, Common Yellowthroat was the number one species with 19 individuals. Red-eyed Vireos swooped in second with 7 and Painted Buntings in third with 4. 
The crew enjoyed two first of the seasons both caught right at the end of the day today. The first was a hatch year male Summer Tanager with some interesting aberrant plumage including some pale feathers on the head and white greater coverts. He also sported bright pink legs and feet, differing from the grey or black this species usually has. The other exciting capture was a young female Blackburnian Warbler, a species each station will only capture a few of each year.
