Histological structure of the digestive tract of waders (Aves, Сharadrii)
Histological structure of digestive tracts of 12 species of waders (Aves, Сharadrii) has been studied: Pluvialis squatarola (Linnaeus, 1758), Charadrius hiaticula (Linnaeus, 1758), Recurvirostra avosetta (Linnaeus, 1758), Tringa ochropus (Linnaeus, 1758), T. glareola (Linnaeus, 1758), T. nebularia (...
