Calidris

 

a genus of birds of the family Charadriidae of the suborder Charadriiformes. The body is 12-23 cm long and has long, sharp wings. The bill is straight or slightly decurved. The coloration is dark with mottled markings above and white below. Sometimes the underparts are reddish yellow or black. There are 17 species, distributed mainly in the tundras of Europe, Asia, and North America. Fifteen species are found in the USSR. Most species migrate south for the winter, some traveling as far as the southern tip of Australia, Africa, or South America. The birds build nests on the ground. A clutch contains four eggs, which are incubated by both the male and the female. The birds feed mainly on small invertebrates, which they dig from the top layers of the soil or gather from the ground.

Solo 5 especies mostraron valores de coeficiente de variacion superior a 20 % (Calidris fuscicollis: 20,3 %; Recurvirostra americana: 20,6 %; Porphyrio martinica: 24,6 %; Anas acuta: 25,5 % y Podilymbus podiceps: 25,6 %).
It also was found that, while pursuing dunlins (Calidris alpina), aerial attacks (refered to as low stealth attacks or flock chases) were used most frequently in hunting these shorebirds that remained close to the ground (Buchanan et al., 1988).

1996), a decrease in time available for foraging in less suitable sites (as reviewed by Frid & Dill 2002), and we could expect a higher nocturnal activity rate to compensate for this, as has been found for the sanderling Calidris alba (Burger & Gochfeld 1991) and the snow goose Chen caerulescens atlantica (Belanger & Bedard 1990).We did not observe this in our study, likely because the high available earthworm biomass in meadows (about 1 ton/ha; Granval &Bouche 1993) does not constrain the instantaneous intake rate and easily allows woodcocks to compensate for a loss of diurnal foraging.
