Ruby-throated Hummingbird (derbyshire)
Late May and early June typically features a gradual slowdown of bird migration in terms of abundance and species richness. This is the period of spring migration when flycatchers, vireos and thrushes replace warblers and sparrows as the most prominent species. During the past week there was no such slowing of migration however warblers were few and the aforementioned late spring species were abundant. On May 27 the first Yellow-bellied Flycatcher of the season was recorded along with an unusual TTPBRS sighting of an American Bittern. A shift to south winds on the 28th brought in more birds to Tommy Thompson Park as 92 birds were banded which included high numbers of Swainson's and Gray-cheeked Thrush, Gray Catbird and Red-eyed Vireo. A total of 40 Red-eyed Vireos were tallied on the day along with 18 American Redstart and a record high 14 Mourning Warblers. The second record of Green Heron for TTPBRS was also detected on this day. Overnight migration was heavy on the night of May 28/29 which led to the banding of 85 birds on the 29th. Eastern Wood Pewee (2 banded), Yellow-bellied Flycatcher (8 banded) and Traill's Flycatcher (50 observed) were well represented along with another high count of Red-eyed Vireo. A total of 92 birds were banded and 6 recaptured on the 30th of May which included 12 Gray-cheeked Thrush along with 27 Swainson's Thrush and the first Yellow-billed Cuckoo since 2004. The weather pattern of high temperatures and heavy fog continued on the 31st when TTPBRS staff encountered another decent passage of late spring migrants. Highlights of the first day of June included the arrival of Alder Flycatcher and the capture and banding of 7 Yellow-bellied Flycatcher. On the final day of the update period, migrant species were fewer and most of the birds observed were active breeders. The TTPBRS study area has "greened out" very nicely, the honeysuckle and dogwood shrubs are in full flower and the amount of nesting activity is quite spectacular! The migration monitoring program will run through June 9 for the spring and then re-open for the fall on August 5.
Foreign Recovery- Marcel Gahbauer of McGill Bird Observatory informed me that a Ruby-crowned Kinglet banded on October 9-2005 at TTPBRS was recovered at his station in Montreal on May 2-2006. This represents the second RCKI banded at TTPBRS that has been recovered elsewhere. This is interesting given that fewer than 20 Ruby-crowns banded in Canada have ever been recovered.
