Our efforts on Ship Island focus so heavily on tern monitoring, that we seldom mention the other species that spend their summer on the island. We made an earlier post about migrants, but I’d like to outline some of our everyday, non-tern sightings.
Two species of warbler are our brightest residents, their brilliant colors visible even through the growing foliage. Yellow Warblers, as their name implies, are a fantastic yellow hue throughout, with some red or brown markings on the breast. We have at least one pair in the grove, where the female was gathering nest material earlier in the season. A few Common Yellowthroats’ “Wichety-wichety-wichety” can be heard around the island, with them making an occasional feeding foray just outside the cabin window.
While not as striking as the warblers, three sparrow species make their homes on Ship, with at least two of them breeding here. Our two dozen or so Song Sparrows are one of the most common streaky sparrows found throughout much of the U.S. and Canada. Their reddish caps and tails set them apart from our equally numerous Savannah Sparrows. Savannah Sparrows are smaller and have a bright yellow spot right above their eye. A more recent arrival has been the Nelson’s Sparrow, of which we have seen only two. Smaller even than the Savannah, the Nelson’s have a strange call somewhere between a hiss and a sigh that we can often hear near the small wetland in the middle of the island.
Terns are often lauded for their aerial acrobatics, but we have at least one pair of nesting Bank Swallows which can match them zig for zag. Much smaller than the terns, the swallows zip around the island gulping up small flying insects and turning on a dime. Their nest is near the top of the bluff, where they have excavated a small hole.
Several shorebird species make use of the island’s tideline for foraging, but only one species, the Spotted Sandpiper, nests here. Their peeping call and constant tail-bobbing set them apart from other species. We have found two nests and suspect that there are at least three more, hidden under tufts of grass.
No island bird post would be complete without mentioning our Mallards. A well-known and common duck throughout North America, we have at least three females currently roaming the island with clutches of ducklings.
Until next time!
