For those going to look at the falcon reported today in Calverton, I would like to expand on Angus' directions: The bird spent all of its perching time on the high tension poles that run through the agricultural fields along Hulse Landing Road north of Rt 25A. The bird ranged from Hulse Landing Rd to the tree row at the edge of the field about 1/2 mile west, which can best be viewed from Sound Ave.
In addition, if any birder has ties to the falconry community, it would be good to check to see if anyone is reporting a lost bird that resembles the Calverton falcon.
