Bird Haven and Flycatchers

Our furthest nestbox site, Bird Haven, was just set up this year, but the nestboxes are already very popular with the birds up there. The site is more rural and quiet than our Putah Creek spots, especially during the songbird breeding season. We’ve gotten nests from house wrens, tree swallows, and an ash-throated flycatcher up there so far.

The eggs in our ash-throated flycatcher camera nest in Winters have hatched. The female has been hard at work feeding them a lot of moths while keeping the nest clean and warm. They’re growing quickly, and they’ll be banded tomorrow! We leave nestlings alone for a couple of weeks after banding to let them fledge, but this time with our camera, we’ll be able to continue to watch them even after that.


The female ash-throated flycatcher brings a moth to her small nestlings. They’re about three days old at this point.


The nestlings have grown a lot in a few days. Here they are shown at six days old.

Meanwhile, all of our sites are still busy with chicks to band! Our interns and field leaders are doing a great job keeping up.
