Eric Rasmussen shares an account of the bird crew's initial 2016 Hummingbird banding research efforts.

Bird Field Note 5/15/16 Hummingbird Banding Update Eric Rasmussen

Hummingbird banding began on April 26th at the Clubhouse Floodplain. On the 27th, we banded at our second site, Baldy Mountain. Each banding session is five hours and occurs every other week. Eric holds the first male Calliope banded at MPG (below).

The first two weeks (four banding days) were a success. We caught 13 Calliope’s, and one male Rufous. We did not recapture any birds between sessions, so we assume most of these birds are migrants. We expect to start capturing local breeders in the coming weeks, including Black-chinned Hummingbirds.

We set up a Hall trap, designed to drop over a feeding hummingbird when triggered. Trappers keep a watchful eye on the two trap feeders.

Once triggered, we carefully reach under the net to remove the hummingbird.

The hummingbird is placed in a mesh bag for transport to the banding table.

After processing, each bird is given an opportunity to fill up on nectar before release.

Each bird is handled between 3-7 minutes. Sometimes they become acclimated to our touch and need prompting to fly.
