Migration Monitoring at TTPBRS-August 26-September 1

It was a slow week for migrants at TTPBRS as indicated by the average daily banding total of 17. Winds were primarily from the south and west which likely kept birds off the peninsula. Numbers of Red-eyed Vireo increased as several were captured daily during the week. This is the time of year at Tommy Thompson Park when Ruby-throated Hummingbirds are most abundant. Hummers started hitting the nets on the 21st and have been captured daily since then. We usually capture the last one around mid-September so keep your feeders well stocked! Despite the decreasing water levels, shorebirds have been rather scarce at the park this fall. Single Solitary Sandpipers were observed on the 26th and 27th which was unusual (3rd and 4th records). The research station was closed on the 31st due to rain and high winds. The following day was a busy one at the station as 6 new arrivals were recorded and 57 total birds were banded. There were no dominant species on the day but very good diversity as 27 species were captured and 67 total species recorded. The highest one-day species total for fall 2004 was 66 on September 18. Warblers were strongly represented but the highlights were a single Long-tailed Duck (early) and a single Common Nighthawk. The nighthawk sighting is just the third record for TTPBRS and the first ever for fall monitoring! This species is regular in the city and often seen before dawn flying over the spine road at the spit but they rarely venture over our little corner. 
 
The storyline so far this season has been higher numbers of many warbler species than the previous two fall seasons at the station. The final count of Yellow-rumped "Myrtle" Warblers could be very impressive when all is said and done as their movement has continued unabated since early August! It may have been an exceptional breeding season this year and if so we can expect some good days ahead.....
