Harmar HatchWatch Clock 2019
|Hr8 Age||140 days 1 hour 34 minutes 53 seconds|
While there is no cam on the Harmar nest this year, ground observers at Harmar reported behavior that is consistent with egg laying and incubation on 2/28 at 4:42pm. On April 5, ground observers report adult behaviors consistent with a hatch.
The Hatchwatch Clock counts UP from the time the egg is laid.
- Bald eagle eggs take 35 days to hatch on average.
- As we get closer to day 35, begin to watch for a ‘pip’ in the egg.
- First eggs may take a bit longer to hatch than later eggs as they sometimes are not intensely incubated until the arrival of the second egg, the brood patch may also be less well developed, and the initial incubation temperature may be slightly lower.
- The range for hatching is 34-41 days; only rarely would an egg hatch outside of this range.
