The biologists up at Environment Canada recently wing tagged over 150 waders and are now asking for birders to report any sightings of these birds.
From one of the biologists-
50 young Great Blue Herons and over 100 young Great Egrets from three sites in Lake Huron have been marked with Green or Orange wing-tags in the last month; each tag carries a unique number-letter combination. New York and Pennsylvania birders are asked to watch for these birds and send details of any sightings (date, time, location, observer, color of tag and number-letter combination) to email@example.com. Also, please report any evening roosting sites and feeding aggregations of 6 or more birds.
So if you see any green or orange on the wings of a wader, be sure to check it out and help the researchers out by reporting them!
