Great Blue Heron
The Great Blue Heron is a species of concern in Montana. Their concern status is a result of a 2.2% annual population decline measured by Breeding Bird Surveys from 1966 – 2010. The colonial bird relies on intact rivers and stream side habitat to establish their nesting colonies, with one impact, it can affect many at one time. We have partnered with the Montana Natural Heritage Program to ensure a better state-wide coverage of annual heron rookery surveys. We are looking to confirm potential new rookeries, populations, conservation opportunities, and threats for our Great Blue Herons in Montana.
The Great Blue Heron Rookery survey season will take place from May 1- June 30.
