Yes, Lara. It seems the two in the nest are quite cozy now.

I think E2 (the one that fledged early) was the one who stayed as far away from the other 2 as possible.

Some photos were put up yesterday, stills. So I did a screen capture myself.
There are at times situations where the smaller E3 helps to preen the Large E1. Also they do a beak kissing.. not pecking, but some sort of kissing it looks like. Yesterday they were quite a pair sleeping most of the day, getting stronger. Today there may be a fledge.

It was mentioned in chat that Karel works for Cornell in the alumni division. And also can sing and play the violin. But alas he is married...
.
Yes the area where the birds are is beautiful with those gardens, Plant Sciences Building, and the old building with the "door to Narnia" as Karel affectionately calls it. He also calls it the "door to nowhere". LOL

Also yesterday afternoon BR Mom actually FED them a chippie! Haven't seen her do that in a while now. It was rather sweet. It is like she "knows" the fledge will be very soon now.

Oh, I just went there this morning and E2 is on the white building window ledge like the first day of fledge. I guess he will try for the nest today? Some peeping going on this morning... BR Mom is on the roof of that building too.
E2's crop looks large, so he may have been fed this morning, earlier.
