Free PMC article.
Here, we focus on several ecologically specialized taxa or 'call types' of red crossbills (Loxia curvirostra complex), one of the few groups of birds providing much evidence for ecological speciation. Call types differ in bill sizes and feeding capabilities, and also diffe …

Species composition of dabbling duck assemblages: ecomorphological patterns compared with null models.
Pöysä H, Elmberg J, Nummi P, Sjöberg K.
Pöysä H, et al.
Oecologia. 1994 Jul;98(2):193-200. doi: 10.1007/BF00341472.
Oecologia. 1994.
PMID: 28313977
Observed spacings in terms of body length, but not in terms of bill lamellar density, were greater than expected on the basis of null models. ...Patterns in bill lamellar spacings were not related to food abundance nor to food size diversity. ...

Foraging activity patterns in the goosander (Mergus merganser) and the red-breasted merganser (M. serrator) in relation to patterns of activity in their major prey species.
Sjöberg K.
Sjöberg K.
Oecologia. 1985 Aug;67(1):35-39. doi: 10.1007/BF00378448.
Oecologia. 1985.
PMID: 28309842
Their diurnal activity correlated with the activity of their major prey, the three-spined stickleback.Both merganser species utilize a specialized foraging technique, i.e. probing the river-bottom with the bill, to catch hiding fish more or less at random. This behaviour p …
