Migration Monitoring at TTPBRS-August 12-18

It has been a very interesting month of August at the research station as temperatures have been below average and we have had higher numbers of warblers than previous years. That being said, our banding totals are consistent with the August average (lowest month of the "field" year). Despite the rain cutting our net hours in half on August 12 we banded 29 birds which included good numbers of Traill's Flycatcher (11) and Yellow Warbler (14). Higher than normal numbers of Myrtle Warbler continue to pass through the park as daily totals have hovered around 10-20 individuals. The nets were very quiet on the 13th however 6 new arrivals for the fall included a singing Alder Flycatcher (1st fall record for TTPBRS) and an Upland Sandpiper (1st record for TTPBRS). 7 Short-billed Dowitchers on the 14th were new for the station checklist. The highlight of the day was the biggest concentration of swallows in the three year history of the migration monitoring program. Barn Swallow (620), Northern Rough-winged (150), Bank (120) and Tree Swallow (25) were observed migrating directly over the banding lab and along the north shore towards the lighthouse. Yellow-bellied Flycatchers started appearing on the 14th and were captured daily throughout the remainder of the week. 25 birds were banded on the following day which included season firsts of Mourning Warbler and Chestnut-sided Warbler. A total of 10 warbler species were observed or captured.  Strong winds on the 17th limited overall capture rates however a good passage of warblers were detected including the seasons first Black-throated Green Warbler. Remarkably, 41 Myrtles were tallied on the day! Favourable winds preceding the 18th resulted in the busiest day of the season so far as 40 birds were banded of 19 species. Numbers of Eastern Kingbird, Baltimore Oriole (6 banded) and American Goldfinch were significant.
