I arrived at Quarry Lake in Pikesville around 6:30pm on 6/24. My main interest was the Green Heron nest as well as the two Great Blue Heron nests. The Green Heron pair have now laid 4-5 eggs in the nest. Based on this and previous observations at the site I would estimate the eggs were laid between 7-10 days ago. The Great Blue Herons have two nests in the same tree. One has a growing chick (just one) that I first saw on 6/10 (though it was reported by others before that) while the other nest is nearly always being sat on as if the bird was sitting on eggs. I am relatively new to the ins and outs of birding but I am thinking at this point either a) the heron just really likes sitting in the nest or b) it is sitting on some dud eggs.
Here is the overview of what I saw:
