Antbutterflies: butterflies that follow army ants to feed on antbird droppings.
نویسندگان
چکیده
Females of three species of tropical rain forest ithomiine butterflies orient to swarms of army ants (Eciton burchelli) and feed on bird droppings found there. The antbirds associated with swarm raids of these ants provide a predictable source of droppings, an otherwise sparsely distributed resource.

The 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...

How diverse are myrmecophiles? In 1894, Erich Wasmann, an Austrian Jesuit priest and one of the pioneering students of myrmecophiles, documented 1,177 ant guests, and the list has grown at an astonishing rate ever since. Myrmecophily has evolved independently in a large number of taxonomic groups, including flies (Figure 1A), beetles (Figure 1B and C), crickets (Figure 1D), butterflies (Figure ...
متن کاملSpecializations of birds that attend army ant raids: an ecological approach to cognitive and behavioral studies.
Tropical birds forage at army ant raids on several continents. Obligate foraging at army ant raids evolved several times in the Neotropical true antbird family (Thamnophilidae), and recent evidence suggests a diversity of bird species from other families specialize to varying degrees on army ant exploitation. Army ant raids offer access to high prey densities, but the ant colonies are mobile an...
