Breeding Anhinga pair vs Great Egrets – photo by Valerie Doane

I’ve seen a male and female Anhinga, I assume a mating pair, on Jenkins Point Road in the lagoon rookery on the right.  You know better than I that there are only a few Egret nests in that rookery.  I noticed on several different visits over the last 10 days or so that the Anhinga pair was sometimes sitting on a nest and sometimes they were not and sometimes they were in a big time squabble with a pair of Great Egrets over the nest!  I have photos of the squabble on June 1st.  I swear the Egrets and Anhinga pair were fighting over the nest!

I was wondering about a few things and thought perhaps you might have some insight on the following:

1.     Do these two species often steal each other’s nest? 

2.     Do Anhinga’s typically nest in the same rookery as Egrets?

3.     Isn’t it late in the season for chicks to hatch?
