Spring is here, and we are patiently waiting for our tagged herons to return from their wintering areas. Here's an update explaining why we haven't seen them yet.

Have you heard of Cornelia, an adult female great blue heron tagged with a GPS transmitter, who nests in Maine and migrates to the Bahamas for the winter? She is one of ten other herons who’ve been equipped with GPS transmitters by Maine Department of Inland Fisheries and Wildlife (MDIFW) to learn more about heron movements, habits, and habitats in Maine and beyond. The project began with the help of a Maine Outdoor Heritage Fund grant and many partnering schools, and is part of MDIFW’s ongoing efforts to understand the status of great blue herons in the state – especially along the coast where their population has declined by 89% since the 1980s.

As a biologist, I know death is as much a part of the life cycle of all organisms as life itself, but it can still be difficult to contend with especially after you’ve “gotten to know” an individual animal by following its movements for nearly five years. That individual is Nokomis, a great blue heron we tagged with a GPS transmitter in 2016.

Harper, the GPS-tagged Great Blue Heron, has done it again! Last fall she impressed us with her 38-hour nonstop flight over the open ocean. This year, she has gone above and beyond, flying for 68 hours and 2,030 miles nonstop from Quebec to Georgia.

The following story was written by Mia, a fourth grade student at Friends School of Portland. Mia helped with the field work leading up to the capture and tagging of "Harper" the great blue heron, in Harpswell. She was also there the morning Harper was tagged with a GPS transmitter. Thank you, Mia, for sharing your perspective!

Three years ago, MDIFW embarked on a heron tracking project, which has since redefined how many Mainers view great blue herons, understand their habitats and movements within the state as well as beyond our nation’s borders. Prior to this project, we knew little about where herons wintered, how many years they may nest in the same colony, how far they fly to forage. Additionally, we knew little about nesting, post-breeding, migration and wintering seasons.

For those who may be late to the party, “Harper” is an adult female great blue heron who was captured and tagged with a GPS transmitter in Harpswell, Maine, by IFW biologists with the help of students from Harpswell Coastal Academy and volunteers with Harpswell Heritage Land Trust.

For nine students at Harpswell Coastal Academy, Wednesdays in May meant donning knee-high boots, venturing to a nearby wetland, and hoping for signs a hungry great blue heron had been there. As part of a spring class elective, these students were dedicated to helping MDIFW ultimately tag a great blue heron with a GPS transmitter as part of an ongoing project to better understand heron habits in Maine.
