Report Nesting Ospreys

Did you know that ospreys suffered through the DDT pesticide crash and recovery just like bald eagles and peregrine falcons?

Ospreys are doing much better now than they did in 1986 when there was only one nest in Pennsylvania — but how much better are they doing?  That’s where you come in.

The Pennsylvania Game Commission monitors this State Threatened species and they need to know where ospreys nest, especially in the western part of the state.

This PGC map shows the known nesting sites in 2015.  Look at the gaps!   For instance, is it possible that no ospreys nest in Armstrong County, home to the Allegheny River and Crooked Creek Lake?  I’ll bet they nest in the county but PGC doesn’t know about them.


Help the PA Game Commission fill in the map by reporting nesting ospreys.  Download the  Osprey Nest Survey Form (PDF) along with the Nest Observation Protocol (PDF). Submit your completed survey forms to

And please don’t assume someone else will report a local nest.  It’s up to you!

  1. I will be keeping a watchful eye out locally. I did observe an osprey hauling a trout towards a possible nest yesterday afternoon while fishing the Allegheny up North in Potter county.
    ! Flew right over me.
