Migration Monitoring at TTPBRS-Oct 14-20

It has been our busiest fall ever at TTPBRS in terms of both the monitoring and education. Migrating birds continued to pass through the count area in high numbers this past week and we have also had a steady stream of school kids coming down as well. Kinglets were abundant on October 14 as ~100 each of Ruby and Golden-crowned Kinglet were recorded. Hermit Thrush and Brown Creeper were also present in good numbers. The first American Tree Sparrow of the fall was banded on October 16th along with 87 individuals of other species. Most interesting on the day was the capture and banding of 20 Black-capped Chickadees which was a record high one-day banding total (previous mark of 10 on November 1-2004). Northwest winds on the 17th probably assisted in bringing another influx of migrants as 160 birds were banded and there was some flyover activity also. Pine Siskin and American Pipits were heard flying over throughout the morning although still in small numbers. Chickadees, Kinglets, Hermit Thrush and Dark-eyed Junco were the primary species moving that day. Speaking of Chickadees, an impressive 55 were banded and 120 were tallied on the day! We were clearly in the midst of a chickadee invasion as numbers like this had never been seen before at TTPBRS. More Chickadees and kinglets were on the move the next day although in lesser quantities. The slowest day of the week was October 19th as 23 birds were banded. This day featured the first substantive counts of waterfowl which included both species of Scaup, Long-tailed Duck, Common Goldeneye and Bufflehead to name a few. The 20th featured another record breaking day at the station for Chickadees as 81 were banded! The Black-capped Chickadee is commonly considered a resident species however they do migrate and during October and November in some years their numbers in eastern North America can be significantly higher than "normal". These irruptions are attributed to seed crop failure in the north as well as higher breeding productivity.
 
Northern Saw-whet Owl Monitoring has begun for 2005 and thus far we have banded 31 owls in 7 nights of coverage.
