Helpers: With bluebirds, the young from previous broods may help feed subsequent broods. This can make it easier to support multiple broods.

How many broods can a bird have in a year?

If conditions and the food supply allow, a few species will raise up to six broods a year. I’m talking about you, Mr. & Mrs. Mourning Dove. Bluebirds can do four. Robins can do three. Other thrushes can manage two. Maine summers are too short to allow maximum re-brooding, but a lot of species can accomplish two broods per year.

How many babies can a Bluebird have from one nest?

In Oregon, 38.5% of nesting Western Bluebird females fledged at least one offspring from a single brood, 29.4% from two broods, and 3.7% for 3 broods. NOTE: Unless birds are banded, it is difficult to know whether the next nest in a box was from the same pair (or a different male/female.)

How long does it take for a Bluebird to fly?

Young bluebirds grow fast, but they usually cannot fly on their own until about 20 days. (It is safest not to open the nest box after their twelfth day to prevent premature fledging and subsequent exposure or predation.)

How long does it take for bluebirds eggs to hatch?

Sometimes, the bluebirds will just build a new nest on top of the first nest containing infertile eggs. Then, the bluebirds will start to hatch! This will occur over a couple of days, but not much more. After the birds are all hatched, the female will continue to brood them (sit on the nest) for several days.

How long do Bluebirds feed babies after they leave the nest?

(Bluebirds continue to feed their young for about 28 days after they leave the nest). The availability of more food, or higher quality food, increases the likelihood that the parents will start another brood. A healthy bird in good condition may be more likely to start another brood.

When do Bluebirds lay eggs?

The overall timing of egg-laying throughout the Bluebird’s range reflects the timing of nest building. Egg-laying begins during February and March in the warmer southern states and March and April in the northern and colder states.

When do Bluebirds fledge in Michigan?

A. Bluebirds can still fledge in Michigan as late as mid-August, depending on the weather and food availability. Further north, such as the Upper Peninsula, this last fledging date could be 1 to 2 weeks earlier.

Do all Bluebirds nest in cavities?

All bluebirds are classified as “cavity nesting birds”. This means that their natural choice in nesting in the wild is some sort of hollowed out cavity in a tree.
