CAPTAIN SAM'S
It was a relatively slow day at Captain Sam's with only 11 new birds and 5 recaptures of 9 different species.  We captured 4 more Prairie Warblers this morning which has been our most commonly banded species so far this season.  We banded adults of both sexes during the same net round which gave a good opportunity to compare their plumage.  Adult males are bright yellow on the breast and face with very distinct black streaking along the flanks.  They also have two black stripes on the face:  one going through the eye and the other creating a "u" shape under the eye.  Adult females can be fairly bright yellow too but usually not as vibrant as the males.  They also have similar markings to the male but the stripes on face are grayish olive in color and the streaking on the flanks is less pronounced.  Males have large reddish spots on their back, while females lack spotting or the spots arereduced in size. For more information on ageing and sexing Prairie Warblers, click this link from a post from 2012.

LITTLE BEAR
It was another slow day at Little Bear this morning and another day we had to close early due to heat. We ended up catching 18 new birds and 3 recaptures of 9 species, with resident species making up most of the birds. We did catch a couple Carolina Chickadees and Tufted Titmice, which were firsts for the site this season. We also found time to set up a new net lane as we plan on having 20 nets up and running soon, instead of the 15 we have now. It looks to be a hot weekend so we are expecting the bird numbers to stay low as we head into next week, hopefully giving us plenty of time to get the rest of the nets set up before the other members of our crew arrive on Saturday.
