Migration Monitoring at TTP-June 3-9

This is the final update for spring 2005 as our last day of coverage was June 9. We will re-open the research station in early August for fall migration.
 
Given the unusually high level of bird actively last week at TTPBRS we weren't quite sure what to expect during our final week. Not surprisingly the remaining days of the spring season were quiet as banding totals peaked at 30 on June 5 and reached a low of just 3 on June 9! The primary species encountered in the first half of the period were Gray-cheeked and Swainson's Thrush, Magnolia, Wilson's and Yellow Warbler. Rather suddenly on June 5 the Yellow-bellied Flycatchers finally arrived at the station as 7 were banded on this day followed by 7 on the 6th and 3 on the 7th. Small numbers of Traill's Flycatcher were also associated with this movement. Unfortunately, a late push of Red-eyed Vireo didn't occur during the final week. Capture totals of this species were way down from last years total of 60, only 5 were banded this year. For the final few days of coverage migrating birds were hard to find as point count and census surveys yielded mostly breeding birds.
 
Recovery-As mentioned earlier in the season on May 18 we recaptured an ASY male American Redstart that was not banded at TTPBRS. We have discovered that the bird was originally banded on September 29, 2000 in Georgia, U.S.A. Based on all TTPBRS recoveries, this one is the furthest in terms of distance from the station and also the oldest (~4.5 years between banding and recovery). 
 
Acknowledgement-It has been another great season at Tommy Thompson Park and volunteers and staff can be proud of what was accomplished. Our coverage was excellent once again and we were able to offer interpretive talks and bird banding demonstrations to 363 people! As it turns out, spring 2005 was our busiest spring on record (2003-2005), however our totals were remarkably similar to spring 2004 (see below). Many thanks are due to the volunteers and to Seabrooke Leckie for their essential support this season!
