migration is still quite slow but there's good news! locally breeding species are rolling out their 2025 model line with the following fledgling notes in recent days:
Allen's Hummingbird - Mount Sutro 4/20 Mourning Dove -Corona Hill 4/22 Dark-eyed Junco - 4/11 Bernal Heights Song Sparrow - 4/13 Pine Lake Park Nuttall's White-crowned Sparrow - 4/23 Sunset Reservoir
Speaking of Allen's Hummingbird, this species was noted breeding on Corona Hill for several years starting around 2015 but not noted since 2019. Imagine my surprise when I discovered a fledgling Allen's yesterday morning (4/22) on the north side of the hill. Any speculation that it may have dispersed from somewhere outside the park was dispelled when later in the afternoon I spotted an adult female Allen's, collecting nesting material and carrying it into the cypress tree visible out the window of my office. A humbling experience to know that despite daily birding at this site a hummingbird can pull off breeding right under my nose.
a few recent migrants:
Ash-throated Flycatcher - Buena Vista Park 4/18 Chipping Sparrow - Corona Hill 4/16 Bullock's Oriole - Laguna Honda Reservoir 4/15, Corona Hill 4/18
An Acorn Woodpecker has been at Buena Vista Park since last September. Acorn Woodpecker is currently only known to breed at Lafayette park in the Northeast part of town but folks should be on the lookout for them colonizing new areas.
