Study Of The Foraging Behaviour Of Birds With Emphasis On Northern Grey-Headed Sparrows (Passer Grisetis) In Mouau Environment
ABSTRACT
Bird species in Michael Okpara
University of Agriculture, Umudike (MOUAU), were studied and observed for their
foraging behavior. A total of 10 species were encountered and of these, 8
featured and could be termed as resident birds. Passerine birds were observed
to forage on ground in open grasslands using three (3) selected sites in MOUAU
environment. Observations were recorded and analyzed using Pearson correlation.
Emphasis on Passer griseus revealed that group size and vigilance were closely
related, there was a significant effect (n10, r0.949, pO.000), correlation is
significant at the 0.011eve1 (2-tailed); vigilance had a significant effect on
feeding rate (n=10, r=0.798, p=O.007), significant at the 0.011eve1.There is a
higher relationship between vigilance and feeding in field 1 than in field 2
(n10, r0.665, pO.036; r0.328, pO.355). Vigilance decreased as group size
increased, and as vigilance decreased, pecking rate increased. The smaller the
group, the higher the vigilance, but vigilance reduced in field 1 having cover
less than meter away. Overall the present findings suggest that bird foraging
behavior is dependent on the nature of the microhabitat, group size and
vigilance.
