Rare and Notables – MAR/APR 2024

In typical fashion, late March and early April provided a variety of migrant waterfowl at Flathead Valley hotspots. Eurasian Wigeon were seen at multiple sites, and a hybrid wigeon was photographed at Church Slough. Greater White-fronted Goose and the Siberian form of Tundra Swan made appearances in West Valley. Early arrivals included Williamson’s and Red-naped Sapsuckers, and Loggerhead Shrike; a Snow Bunting and Lesser Black-backed Gull lingered. See also: https://ebird.org/region/US-MT-029?yr=all

  • What to Expect – April/May 2023

It’s time to put out the hummingbird feeders, as Earth Day (4/21) usually heralds the first arrivals. The number of arriving migrant species will start to increase exponentially by the beginning of May, with Blue-winged Teal, Vaux’s Swift, Barn Swallow, Vesper and Savannah Sparrow, Cassin’s Vireo, and the first warblers due any day. Most breeding species will have arrived by the time I prepare the next installment of this summary, May 16th; only our latest arrivals (Willow Flycatcher, Red-eyed Vireo, Common Nighthawk) wait until the end of May to show up in northwest Montana.
