CAPTAIN SAMS
It was a much busier day today compared to yesterday with 78 new birds and 20 recaptures of 14 species. We had another surge of Yellow-rumped Warblers today with 59 of them banded. We also banded a late Red-eyed Vireo which was had a significant amount of fat. I doubt we will see that bird again as it is in prime migration condition and it needs to get to South America.
The highlight of the day was a Vesper Sparrow! This was only the 2nd one ever captured at KIBS with the last one banded back in 2012. This bird was actually captured in one of our "Tree Swallow" nets. This net is located out in the saltmarsh along a wax myrtle shrub on a little patch of high ground. I don't normally associate Vesper Sparrows with the saltmarsh but I guess during migration, birds can show just about anywhere.
Liz stayed a few extra days after we shut down Little Bear to help with Captain Sams. We appreciated her help! It will just be Michael and myself for the remainder of the season.
