Effects of forest heterogeneity on occurrence and abundance of the scale-backed antbird, Hylophylax poecilinotus (Aves: Thamnophilidae), in the Amazon forest.
The antbirds survive by tracking army ants, which hunt in large swarms and are capable of killing just about anything in their paths.
The antbirds have several calls, some to let fellow antbirds know where the army ants are heading, others to attract mates and still others that are defensive or aggressive to protect turf.
When the researchers played songs recorded from other warbling antbirds
, both males and females were more likely to approach the speaker and to sing in response to same-sex solos than to male-female duets.
For antbirds (Formicariidae), territory sizes were measured for 28 species at Cocha Cashu and 15 species at Limbo.
However, those antbirds also occupied treefall gaps well away from the road (see Fig.
Seddon, who has just been awarded a L'Oreal-UNESCO Women in Science award for her work, and her colleague Dr Joseph Tobias carried out their study by tracking 17 pairs of antbirds
in the Peruvian rainforest.
When Michaela Hau and Martin Wikelski of Princeton University mimicked light changes for Panamanian antbirds in an aviary, as few as 17 minutes of extra light triggered gonad maturation.
Pairs of dusky antbirds, for example, hold territories year-round.
High survival in tropical passerines has been claimed primarily for suboscine taxa, particularly the manakins (Pipridae) and antbirds (Formicariidae).
Longevities of some Panamanian forest birds, with note of low survivorship in old Spotted Antbirds (Hylophylax naevioides).
Most of these insectivores, especially the ovenbirds, woodcreepers, and antbirds
that dominate the sample, feed almost exclusively on small invertebrates (see accounts in Hilty and Brown 1986).
Washington, Mar 13 (ANI): Female antbirds
sing over the songs of their male partners in a bid to prevent their flirtatious messages from reaching single female birds, a new study has found.
Among the antbirds
, population size also varied significantly among guilds ([F.
