Migration Monitoring at TTP-September 16-22

A busy week.....

As anticipated, north winds and cooler temperatures brought more birds into Tommy Thompson Park, especially thrushes and the first of several late fall species. This weather pattern led to 97 birds being banded on the 18th and 95 banded on the 19th. Grey-cheeked and Swainson's Thrush along with Nashville and Black-throated Green Warbler were the dominant species on both days. The migration of Grey-cheeked Thrushes has been particularly impressive in fall 2004 as over 50 have been banded so far (compared to a total of 23 last year). A remarkable tally of 70 species was recorded on the 18th making this the highest one-day species total for fall monitoring at TTP (52 was highest in 2003 on September 26).

Weather for next week looks favourable for more excellent birding and banding at Tommy Thompson Park!
