LONG-BILLED MARSH WREN (Cistothorus palustris) Wren family

[Called also: MARSH WREN, AOU 1998]

Length -- 4.5 to 5.2 inches. Actually a little smaller than the

English sparrow. Apparently half the size.

the back irregularly and faintly streaked with white. Wings and

tail barred with darker cinnamon-brown. Underneath white. Sides

dusky. Tail long and often carried erect. Bill extra long and

slender.

Migrations -- May. September. Summer resident.

Sometimes when you are gathering cat-tails in the river marshes an alert,

nervous little brown bird rises startled from the rushes and tries to elude

you as with short, jerky flight it goes deeper and deeper into the marsh,

where even the rubber boot may not follow. It closely resembles two other

birds found in such a place, the swamp sparrow and the short-billed marsh

wren; but you may know by its long, slender bill that it is not the latter,

and by the absence of a bright bay crown that it is not the shyest of the

sparrows.

These marsh wrens appear to be especially partial to running water; their

homes are not very far from brooks and rivers, preferably those that are

affected in their rise and flow by the tides. They build in colonies, and

might be called inveterate singers, for no single bird is often permitted to

finish his bubbling song without half the colony joining in a chorus.

Still another characteristic of this particularly interesting bird is its

unique architectural effects produced with coarse grasses woven into globular

form and suspended in the reeds. Sometimes adapting its nest to the building

material at hand, it weaves it of grasses and twigs, and suspends it from the

limb of a bush or tree overhanging the water, where it swings like an

oriole's. The entrance to the nest is invariably on the side.

More devoted homebodies than these little wrens are not among the feathered

tribe. Once let the hand of man desecrate their nest, even before the tiny

speckled eggs are deposited in it, and off go the birds to a more inaccessible

place, where they can enjoy their home unmolested. Thus three or four nests

may be made in a summer.
