We obtained the following results:
(1) Food patch depletion and within-group scramble competition for food apparently did not affect patch use.
(2) Within-group contest competition (aggressive interactions related to social-dominance rank) also did not strongly affect patch use.
(3) The number of co-feeders in the same patch consistently showed positive effects on patch use, while food quality did not have consistent effects. These results suggest that the presence of co-feeders enhances foraging success in a patchy food environment.BrillJournal Articleapplication/pdfhttp://hdl.handle.net/2115/51736https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/51736/1/Kazahari%20%26%20Agetsuma%20%282008%29.pdf0005-79591568-539XBehaviour14568438602008enginfo:doi/10.1163/156853908783929188author
