Migration! Millions of birds are on the move, making their way from the tropics of Central and South America to the boreal forests of North America. Warblers, vireos and flycatchers in their brilliant breeding plumages flying over the Central Valley are offered respite in the riparian habitat of Yolo County. Fueling up to continue their journey, April and the first half of May are our chance to hear these migrants’ songs as we walk along Putah Creek in the early morning.
While warblers might steal the show, it was a shorebird that stole the hearts of Yolo birders this month. A RUFF was found amongst dowitchers at the Yolo Bypass (CT), on April 17th. This Eurasian shorebird is seldom found in North America but the Bypass might be one of the best places to find one. This bird stuck around and delighted birders for a week before it continued its journey north.
A Gray and Dusky Flycatcher were both found this April, these two species are Empidonax flycatchers or “Empids” as this genus of flycatchers is known. These are notoriously difficult to identify and require patience and persistence to get down. The GRAY FLYCATCHER was found at Grasslands Regional Park on April 24th (FF) and the DUSKY FLYCATCHER was found the following day at North Davis Farms (ZP, SS).
A BREWER’S SPARROW was a one day wonder at the Mace Bridge access to Putah Creek on April 27th (GP). This small sparrow is typically found in the sagebrush of the Great Basin but got a bit off track and found itself on a barbed wire fence in Yolo. The ensuing search party could unfortunately not relocate this bird.
A special thanks to the following for their reports: Cameron Tescher (CT), Frank Fabbro (FF), Zane Pickus (ZP), Sonjia Shelly (SS), and Gerrit Platenkamp (GP)
