Size does matter when choosing a mate
..., body size and ecology of more than 100 different shorebird species from around the world. They found that in larger shorebirds the battle between males for a mate is highly competitive and larger size offers an advantage over other potential suitors as they battle aggressively on the ground. The evolutionar...Sex and genetics: Why birds are unfaithful to their partners
...lternative mates available. The study on the three shorebird species now suggests that females seek extra-pair copulations to avoid inbreeding depression or other negative effects of genetic similarity. Moreover, it provides a similar explanation for the evolution of quasi-parasitism, suggesting it is a male-d...People linked to new sea otter diseases
... to be lethal in pups and juveniles. The worm is a shorebird parasite that uses sand crabs as an intermediate host. Sea otters usually don't catch it because they prefer molluscs and sea urchins. But people also like molluscs and sea urchins and when these prey are scarce, an otter can eat several sand crabs i...New species of early bird discovered in Mongolia by team of research scientists
...orebirds restricted to near-shore environments and shorebird ecologies. The analysis by Dr. Norell and Ms. Clarke reveals, in fact, that early modern birds were not restricted to a near shore marine or wading bird habitat, but were, rather, small terrestrial flyers. Discovered in continental (not near-shore ...As Hurricane Floyd moves up the Atlantic Coast . . . .
...f hurricanes on birds, USGS biologists expect that shorebird migration has beenseriously disrupted and that many coastal species mayhave been pushed to far-inland sites. Sandpipers, plovers, knots, and othersmay end up feeding and roosting in agricultural fields in eastern Tennessee orKentucky. The endanger...First North Americans Had Chance To Be Avid Birders
...l. "For example, there was not just one species of shorebird butfour different ones indicating a variety of feeding niches in the region." This conclusion is supported by a plethora of contemporaneous mammalian remainsfrom the site, including those of mammoth, bison, horse, dall sheep, caribou,moose, wapiti, s...... a loser in the genetic lottery. But the tropical shorebird has someconsolations: At least some of the young he cares for carry his genes. Sometimes other males raise young that he has sired. Love lost is better than no love at all.
