Take 5: Pretty Spring Peepers

Spring in Massachusetts brings a loud chorus of peeps. Tiny frogs called spring peepers are calling from wetlands. It’s all about lovemale peepers are hoping to attract females.

But there’s more to these frogs than their sounds. They can tolerate cold weather and can freeze nearly solid in winter. They can also change color, switching to different shades of brown and tan. And they’re adept climbers, helped by sticky pads on their feet. Enjoy these five peeper portraits from past editions of our Photo Contest and learn more about frogs in Massachusetts.

Last Month in Birding: February 2016

Here are five incredible bird sightings from last month as suggested by Mass Audubon’s experts.

Yellow-billed Loon (Gavia adamsii)

The largest loon species in the world, this bird breeds on the high Arctic tundra, farther north than our familiar common loon. Scientists still have much to learn about its habits. Outside of certain Arctic and west coast locations, it’s only rarely observed, and sightings from the east coast are almost unheard-of. In fact, it had never before been recorded in Massachusetts—until this February and March, when a yellow-billed loon was found bobbing in the waves off of Provincetown.

Western Tanager (Piranga ludoviciana)

One of our most vividly colored bird species is the scarlet tanager; breeding males are cherry-red and black, and females are greenish-yellow. In the west, the scarlet tanager is replaced by the western tanager. Male western tanagers are yellow and black and only have red pigment on their heads; uniquely, this red pigment comes directly from the insects in their diet. In January and February a western tanager visited a private feeder in Rowley.

Yellow-throated Warbler (Setophaga dominica)

This strikingly patterned bird is a common warbler in the southeastern US. It typically builds its nest in Spanish moss that hangs from tree branches in the open southern woodlands where it lives. The yellow-throated warbler normally winters along the Gulf coast and in Central America and the Caribbean islands—but one was spotted in Amesbury.

Bullock’s Oriole (Icterus bullockii)

This species is similar to the familiar Baltimore oriole, except that the male Bullock’s oriole has a mostly orange face with a striking black eye stripe and a white wing patch. It’s a bird of the western US, but it occasionally interbreeds with the Baltimore oriole on the Great Plains where their ranges overlap. At one time the two species were lumped into one—the northern oriole—before scientists determined that they were genetically distinct. A Bullock’s oriole visited a bird feeder at a private residence in Newburyport.

Mystery Gull

Now and then a bird appears that confounds the experts. Among the gulls standing on the ice last month at Turners Falls, one individual really stood out: a herring gull-sized bird with yellow legs. Experts proposed two possible identities. It could have been a yellow-legged gull (Larus michahellis), a European species that breeds in the Mediterranean and the Azores. If so, the bird had wandered way out of range! The other option was that it was a hybrid—a mix of two species, in this case possibly herring and a lesser black-backed gulls. Either way, it was an unusual sighting and brought some much-needed excitement to sleepy February.
