Herons fighting over nest ownership at Ballston Lake rookery. 

Heron at Ballston Lake, NY rookery. 

One great blue heron was on this nest and another one flew up to land and they were not happy with one another. 

Another heron. Ballston Lake rookery. 

Another shot from the rookery. Honey I'm home!!!! 

Took some shots at the Great Blue Heron rookery near Ballston Lake today. The herons are starting to pair up and steak out their nests for the year. There were quite a few standing on the nests there today. When they pair off, one will stand on the chosen nest and the other will fly off to forage for food. The one on the nest is guarding the nest so the other herons won't steal building materials.
