It’s easy to take GREAT BLUE HERONS for granted. Commonly seen in wetlands, this imposing wader catches fish, frogs, snakes, and more through stealth and the quick action of its long neck and pointed bill. What you likely don’t know is that this species has been expanding its range in Maryland for the last 50 years. In 1977, there were only 14 nesting colonies of Great Blues, and they were all in Coastal Plain counties, especially the Eastern Shore. The 1983-87 DC & MD Breeding Bird Survey (BBS) documented 51 colonies. Tallies from the last DC & MD BBS (2002-2006) found that breeding colonies had increased to 96, including some close-in to the DC metro area. The reasons? Cleaner rivers (and more fish!) due to the Clean Water Act; increasing numbers of artificial ponds, including for stormwater run-off ; increased surveying by the State since the 1980s—and last, but not least, the 1972 banning of DDT, a commonly-used pesticide in the 50s and 60s. The accumulated concentrations of DDT in the food chain of some birds had caused a thinning of their eggshells. This led to low reproductive success rates, with some species suffering significant population declines.

All are invited to join us tomorrow, May 27th at Noon as we mark the birthday of ANS member and scientist/naturalist/writer Rachel Carson. Her 1962 book “Silent Spring” was the catalyst for the US ban on DDT, an act which provided for the recovery of declining species such as Bald Eagles, Osprey, Pelicans, Peregrine Falcons and Robins, in addition to Great Blue Herons.
