Migration Summary for the Period April 29th – May 5th

Louisiana Waterthrush

 

Migrants continued to arrive in modest numbers this week although a good variety of species were noted during the summary period. Early spring birds such as Golden-crowned Kinglet, Brown Creeper, Hermit Thrush, and Northern Junco were mostly absent, but quite a few new arrivals were observed (17 species). It was a transitional week in some respects as we await the first significant influx of neotropical birds including most of the warblers, vireos and flycatchers, and a host of others.

 

It was generally quiet on April 29th with the exception of 55 Yellow-rumped Warblers on the day along with ones-and-twos of four other warbler species. The 30th was noticeably more active when 62 species were tallied in the count area including eleven warbler species, the first Red-eyed Vireos of the spring, and small numbers of Wood and Swainson’s Thrushes. The highlight of the day was a captured Louisiana Waterthrush, which is just PIBO’s second banding record for this species.

 

After a fairly inactive morning on May 1st, migrants once again increased in number on the 2nd and four spring ‘firsts’ were recorded – Ruby-throated Hummingbird, Veery, American Redstart and Chestnut-sided Warbler. A similar morning of activity on May 3rd produced a banded White-eyed Vireo. A Summer Tanager and Louisiana Waterthrush were observed by PIBO staff at Fish Point in the afternoon.  

 

May 4th was also busy with 60 species recorded during PIBO’s six-hour count period, including the most unusual bird of the spring to date – a Lark Sparrow noted at the tip during the morning census. This is a first record for PIBO and, in all likelihood, a new documented species for Pelee Island. The final day of the summary period was fairly uneventful apart from the arrival of the first Orchard Orioles of 2009.  

 

Next week’s summary will be posted on May 14th.
