Migration Monitoring at TTPBRS-April 22-28


"Yellow" Palm Warbler (Derbyshire)

The research station was closed on the 22nd and 23rd due to very high winds and rain. Staff and volunteers returned on the 24th and found respectable totals of White-throated Sparrow, Hermit Thrush and Brown Creeper. On this day Ruby-crowned Kinglets outnumbered Golden-crowns for the first time this spring and there was also a good diversity of sparrows. Despite north winds a total of 77 birds were banded on the 24th which included the first Pine Warbler banded for the season and the first ever banding of "Yellow" Palm Warbler at the station. Higher wind speed (northerly) on the 25th stalled migration once again as just 12 birds were banded before the rain and hail began falling at TTP. April 26 saw the arrival of Northern Rough-winged Swallow at TTPBRS and season firsts of Black-and-white Warbler, Merlin and Purple Martin appeared on the 27th. Also documented on the 27th were higher counts of Ruby-crowned Kinglet, Barn Swallow, Myrtle Warbler and Swamp Sparrow. The weather was quite consistent throughout the update period and continued on the 28th as there were few new migrants and many recaptures. Highlight of the 28th was the second sighting of Forster's Tern this spring (likely the same bird).

Overall the first 30 days of spring 2006 was "normal" for us as April has consistently been the most quiet month at TTPBRS between 2004 and 2006. However banding totals are never an appropriate measurement of success for a project of this kind. What is important is that we have been able to gather a good sample of temperate migrant species that pass through the area in early spring.

The Winged Migration program for grade 5-7 students has been going very well with many excited responses to the Flickers, White-throats, Cardinals, Kinglets and Creepers that we have shown them in the hand! The program will be running through May 12.
