Army Ant Raid Attendance and Bivouac-checking Behavior by Neotropical Montane Forest Birds
—We quantified resident and migrant bird attendance at army ant swarm raids (n 5 48) in a neotropical montane forest. All observations were during seasons when Nearctic migrant birds are present. Bird species differed in army ant raid-attending behavior. Resident bird species attended 2 to 54% of raids, while migrants attended at lower maximum frequencies (2 to 21% of raids attended per species...
متن کاملThe spatial distribution of avian relatives: do obligate army-ant-following birds roost and feed near family members?
The ocellated antbird (Phaenostictus mcleannani) feeds in groups and therefore is an informative species in which to study the biological factors that modulate avian group living. These birds congregate at swarms of army ants to capture fleeing prey, and previous observations suggest that males may be philopatric, feed with close relatives, and defend communal feeding ranges. We assessed whethe...
متن کاملA case of mental time travel in ant-following birds?
Army ant-following birds that inspect bivouacs (temporary nests of nomadic army ants) might provide a novel candidate for studying elements of mental time travel in animals, namely the ability to 1) remember the time and place of specific past events and 2) to use this memory to plan for future actions. Army ant colonies are a rich but unpredictable resource: Army ants do not raid every day, an...
متن کاملPhylogenetic conservatism and antiquity of a tropical specialization: army-ant-following in the typical antbirds (Thamnophilidae).
One of the most novel foraging strategies in Neotropical birds is army-ant-following, in which birds prey upon arthropods and small vertebrates flushed from the forest floor by swarm raids of the army-ant Eciton burchellii. This specialization is most developed in the typical antbirds (Thamnophilidae) which are divisible into three specialization categories: (1) those that forage at swarms oppo...
متن کاملSpecies-Specific Seed Dispersal in an Obligate Ant-Plant Mutualism
Throughout lowland Amazonia, arboreal ants collect seeds of specific plants and cultivate them in nutrient-rich nests, forming diverse yet obligate and species-specific symbioses called Neotropical ant-gardens (AGs). The ants depend on their symbiotic plants for nest stability, and the plants depend on AGs for substrate and nutrients. Although the AGs are limited to specific participants, it is...
