Thanksgiving Bushtits


As we were cooking Thanksgiving dinner this noon, my husband happened to look out our kitchen window at the bird feeders in our back yard. “We have bushtits!”

Bushtits on suet feeder.

These gregarious little birds move around the neighborhood in a small flock. You know they are passing by their flitting flight, and their cheeping “contact” calls.

Male bushtits have dark brown irises…

Bushtits normally eat insects — scale bug, mostly, but spiders, caterpillars, wasps, ants, beetles — anything that crawls. After the 18 inches of snow dumped on the Front Range, though, insects were in short supply.

…while female bushtits have yellow eyes.

And so they resorted to our feeders.

I don’t know whether this is a bit of mealworm suet, or a chunk of sunflower.

In the summertime, bushtits need to eat 80% of their body weight to keep from losing weight. That adds up to a lot of scale bugs.

Either will give her energy through the cold weather.

But in winter they have to eat more. They are probably less choosy about how they get their calories. And are thankful for whatever they find.

Female leaves feeder with a choice morsel.

I think I’ll make sure I’ve got plenty of mealworm suet for them, in any case.

  1. What a treat for us (to see) and for the bushtit (to eat)! Well done on both counts.
