They are monogamous and usually produce one brood each year.

They usually breed between February and May.

The female ones lay about five to eight eggs per clutch.

Their nests are made of moss, spider webs, lichen, etc.

The babies are then fed with spiders and insects by both parents.

The young would be ready to fledge by 16 to 17 days.

Like other bushtit species, they display a very cooperative behavior when it comes to breeding.

Sometimes, the parents may even have one or two helpers to raise their young.

These bushtits do not have territorial calls, but they do exhibit high-pitched calls, trills, and sputters.
