Tyrant flycatchers (Tyrannidae)
Baby great crested flycatchers: from egg to fledgling
A Great Crested Flycatcher lays 4–8 eggs. They hatch after 13–15 days, and the young leave the nest 13–21 days later — about 26–36 days from egg to fledgling.

Stage by stage
- Eggs (13–15 days): 4–8 eggs per clutch. Most songbirds start incubating when the last or second-to-last egg is laid, so the young hatch close together; owls and hawks start with the first egg, so their chicks hatch days apart.
- Nestlings (13–21 days): the young hatch with little or no down and their eyes closed. They grow fast on a diet the parents bring in. In the breeding season great crested flycatchers mainly eat beetles, moths and katydids.
- Fledglings: after leaving the nest, young great crested flycatchers are fully feathered but short-tailed and clumsy. They spend days to weeks on low branches or the ground while the parents keep feeding them.
- More broods: 1 per season.

Found a baby Great Crested Flycatcher?
- Feathered, hopping, can grip your finger: a fledgling. This is a normal stage. Keep pets and children away and watch from a distance; the parents are usually close by.
- Bare skin or only pin feathers: a nestling that fell. If you can see the nest, put it back. Touching it won't make the parents abandon it — that is a myth.
- Injured, cold, covered in flies, or caught by a cat: contact a licensed wildlife rehabilitator. In the US and Canada, ahnow.org finds the nearest one.
- Don't give water or food. Baby birds can choke, and the wrong food can kill them.

Frequently asked
How long do baby great crested flycatchers stay in the nest?
About 13–21 days after hatching. Eggs take 13–15 days to hatch, so it is roughly 26–36 days from the last egg to the young leaving.
How many eggs does a Great Crested Flycatcher lay?
4–8 eggs per clutch, with 1 per season.
Where do great crested flycatchers nest?
Tree cavity or nest box.
What should I do if I find a baby Great Crested Flycatcher on the ground?
If it has feathers and hops, it is a fledgling and its parents are almost certainly nearby — leave it. If it is naked or has pin feathers, put it back in the nest if you can. Call a licensed wildlife rehabilitator if it is injured.
