The Frequent Tern shouldn’t be as frequent because it title could lead you to consider. In truth, in Maryland, these glossy orange-billed seabirds are literally endangered. Though they’re probably the most widespread terns in North America, a household which consists of diving seabirds with angular shapes and lengthy thick payments, Frequent Terns are experiencing a steep and troubling decline.

That’s the reason the breeding colonies and migration relaxation stops that these birds rely upon are so extremely essential. In Maryland, Frequent Terns as soon as relied upon a sequence of coastal islands within the Chincoteague Bay. The islands had been sheltered by a barrier island, making them perfect nesting grounds. Through the winter, storms would flood into the bay and shift sands round, destroying the islands and build up new ones. This sample was destroyed in 1933 when a hurricane carved a gap within the barrier island. From then on, every year the winter storms destroy the islands with impunity and substitute islands can not kind.
Because of this, in Could of 2021, after one more very important nesting island was destroyed, ecologists from the Maryland Division of Pure Sources constructed a raft. Supposed to imitate Frequent Tern nesting sights, the picket raft continues to be in use and has change into a flourishing nesting colony.
This yr is the third yr for the Maryland raft colony. Like years earlier, the raft is residence to a large however delicate colony of Frequent Tern pairs. This yr, a brand new problem has introduced itself. Teenaged seagulls. In line with the scientists monitoring the colony, over 100 adolescent gulls have landed on the island, threatening to upset the fragile man-made habitat. The gulls are doubtless simply searching for a spot to relaxation, however ecologists have been pressured to intervene on behalf of the colony and shoo the gulls away.
That signifies that this yr has seen a lot of scientists, protected with bike helmets, sitting on the raft and shooing undesirable guests. As a result of they’re in such shut contact with the breeding terns, scientists are sometimes swooped at, defecated on, and harassed. It’s a small value to pay for the survival of the colony.
The seagull downside may be a comparatively simple repair, however the unlucky truth is that the raft shouldn’t be designed to be everlasting resolution. It was constructed as a stopgap to stem the speedy decline of Maryland’s Frequent Terns. It’s anticipated to final not than ten years. Ecologists from the Maryland Division of Pure Sources hope that by the point it’s not viable, a extra everlasting synthetic colony may be constructed as a replacement; one which ensures a future for the chicks that started their lives aboard this seabird life raft.
