Mixed—species flocks of birds composed of chickadees, titmice, woodpeckers, nuthatches,
creepers, kinglets, and wood warblers were studied in several habitats in Louisiana …

Two general models have been developed concerning the adaptive advantage of
participating in mixed—species foraging groups. One model emphasizes the increased …

The sociobiology of mixed species flocks is reviewed and used as a basis for evaluating the
adaptive significance of flocking. Virtually all data currently available deal with mixed flocks …

Sm,-In a recent communication Murton (1971 a,'Ibis' 113: 534436) has summarised his
views on the functions of flock-feeding in birds, concluding that the d:, mands of feeding …

Bird flocks are of sufficiently widespread occurrence that a considerable literature has
accumulated on the subject. Recent papers such as those by Short (1961), Moynihan(1962) …

The influence of habitat structure on the foraging behavior of five bird species was studied in
two stands in the Fernow Experimental Forest. Vegetation structure of the stands was found …

(1) In this paper we describe a simulation model of feeding behaviour of birds in flocks. The
model is built using a variety of hypotheses for which some evidence can be found in the …

Two types of competitive interactions occur among species in bird communities: exploitation
and interference. Most theoretical and empirical approaches to the ecology of competition …

Zahavi (1971,'Ibis' 113: 106-109) has recently reviewed the problem of the functional
significance of communal roosting in birds. He is inclined to the view that efficiency in food …

RESULTS The list of instances of interspecific feeding shown in Table 1 was compiled by
searching the literature (Appendix II) and requests made through several ornithological …
