Hints of Fall
Like many birders, I get the summer blues. Breeding season has wrapped up, bird songs have quieted, fledglings are growing up, and frankly it’s too hot for humans and birds alike to be out and about.
But fall is right around the corner. This morning I saw a gaggle of Canada Geese flying silently southward in their V-formation. It reminded me of the flocks of Snow Geese, Ross’ Geese, and Greater White-fronted Geese that winter at the Sacramento NWR. Seeing that V-formation over my apartment was enough to awaken my excitement for the upcoming fall migration season.
Another sign of fall is that shorebird migration has commenced. Already I’m seeing reports of shorebird rarities popping up across the Bay Area. I realized that I’m quite rusty on shorebird ID, so I brushed up my skills by watching a Cornell Bird Academy webinar series on shorebird ID. (Side note: This is an excellent resource if you’re willing to pay $30. It reviews many aspects of shorebird identification, including behavior, habitat, shape, and more.)
One important thing about finding shorebirds is to time your visit with the tides. For example, I like to visit the Emeryville Marina and depending on the tide, I will seek out a different spot. At low tide, a thin mudflat emerges in the harbor, which entices peeps to poke around for goodies. But it’s at high tide that a variety of shorebirds, large and small, collect at the rocks against the trail facing the bay. They are pushed closer to the shore by the rising waters, giving birders a closer look. The same goes with Hayward Shoreline – you want to visit at high tide because the birds are nudged closer to the shore and within viewing range. Take a moment to observe how the tide affects your birds at your favorite shorebird spot!
