Rhinelander Daily News, WI – 3 hours ago
TIGERTON, Wis. – A handful of swallow nests might hold up construction work on a Shawano County bridge indefinitely.

Work on the Tigerton bridge was scheduled to begin Monday. But on Friday the contractor found a number of nests on the structure’s underside, causing a delay until state officials could decide how to work around the federally protected nests.

Putting Your Eggs in Someone Else's Basket


enature.nationalgeographic.com

Cliff Swallows are colonial — that is, they nest in colonies, sometimes numbering in the thousands of birds. In many ways the members of a colony appear to display remarkable social cohesiveness. They work together to mob predators and will even learn from each other where the good food sources are. But if you look closely at a Cliff Swallow colony, you’ll see that this seemingly cooperative community also harbors its share of dastardly misbehavior.

BARN SWALLOWS DO FEMALE BARN SWALLOWS CHOOSE LONG TAILS?

merlejacobs.com Møller (1) found that experimental lengthening the tail of barn swallow males led to earlier mating and therefore an increase in offspring. Since he observed no significant differences in intensity of male-male aggressive encounters among males at the nesting sites he attributed the early mating solely to female choice. This released a flood of […]

Whether the Giants are winning games in big fistfuls, or can’t produce as much offense as a foul-mouthed grandmother, there’s always a good reason to go to their ballpark. I’m not talking about the starlings foraging in the outfield grass, or the hordes of Western gulls that begin gathering faithfully during the seventh-inning stretch (although the best seats for my proposed entertainment are in the upper deck, with the gulls).

Background
Edible bird’s nest (EBN) is essentially the tiny nest woven by Swallows or Collocalia (Apodidae) from gelatinous strands of the bird’s saliva mixed with minor feathers or botanic substances. The birds build their nests wherever they like but mainly on the top of sea caves. Since it contains some of the essential glyconutrients and epidermal growth factors, it is a nourishing food and a booster of health. Southeast Asian people consume it because it promotes tissue and cellular growth as well as speeding up recovery from illness.
