Adult in - Mom? I thought I saw a band as she landed.

Checking the egg and giving it a roll.

From what we've seen on various nest cams over the last 10+ years, I'm quite convinced that eggs do fine being left alone for quite a while (definitely longer than this) in reasonable weather (not raining or snowing, above freezing) - although as has been pointed out, they can be targeted by predators like ravens or even other eagles. But that is rare.


8:42 pm
Second adult in and moving a big stick, which he (I suspect) probably brought.

Mom up to supervise.

I need to focus on work for a while, but will keep an eye on the cams.

One of them left - I think Mom, who may have decided (projecting human thoughts) that if Dad had time to play with sticks, he had time to incubate. Smile

Whichever adult was on the egg just left. Egg is alone.

(Reading back, I think I got confused when they were both there - I thought it was Dad who had stayed, but didn't actually see any identifiers.)


Nice closeup of the egg - thanks, Bev.

I'm happy to see it looking white (if a bit dirty) - my recollection is that the one nest where they may have lost eggs to moisture, the eggs turned sort of brown or gray (just checked - it was Pittsburgh Hays in 2015, and the cam operator Host PixController reported that they received a very interesting message from one of their Facebook fans Susan Shearer. This was her message: "Wanted to give you some info I got from the Raptor Education Center that may be the reason the eggs failed...On Feb. 24th mom stood up and steam came off the nest ..after that the color of the eggs changed ...out of concern I messaged the Raptor center sent them pics of the eggs before the incident and after ..also sent them video of the steam coming off..they had concerns that there was too much moisture and that could cause bacteria that would harm the eggs being they were just a few days old...This makes sense to me" )

I didn't see anything like steam any of the times Mom flew off, and late March in BC is almost always quite a bit warmer than late February in Pennsylvania - and I'm thinking cool rain is less of a risk than warm steam, though that's just my personal opinion with nothing remotely resembling scientific evidence to back it up.


And I see the zoomer has found Mom and Dad - and they do need a bit of time to prepare for egg number 2. Wub

Egg is still alone, and adults are both on the perch by the river.
