Woodpeckers feed primarily on insects, larvae and other arthropods; however, several members of this family include plant products in their diets, such as sap. Among them, the genera Sphyrapicus and Melanerpes include the ...

Several species of woodpecker drill holes in living trees to feed on flows of sap. We describe sap-holes drilled by the White-fronted Woodpecker (Melanerpes cactorum) on plant species in semi-arid woodlands of northern ...

The White-fronted Woodpecker (Melanerpes cactorum) drills holes in branches and trunks to feed on sap flows, providing an energy-rich food resource for other birds. Here we describe ecological and behavioral traits of the ...

The use of anvils for foraging allows access to food that cannot be exploited otherwise by most birds or other animals. This may be especially important in habitats where food resources are scarce or fluctuate seasonally ...

El Estornino Pinto (Sturnus vulgaris) es una especie invasora que fue introducida en Argentina hace aproximadamente 30 años. Esta especie puede usurpar nidos de aves nativas, incluyendo carpinteros (Picidae), mediante ...

One of the causes of nest failure in woodpeckers is competition for nest sites among cavity-nesting bird species, expressed through aggressive interactions. Here I report a case of mortal aggression by an adult White-fronted ...

The White-fronted Woodpecker (Melanerpes cactorum) drills wells in living branches and trunks of trees and shrubs to feed on sap flows, providing an energy-rich food resource for other bird species diverse in ecological ...

Sap is a resource of high energy content that is usually inaccessible to birds, although woodpeckers have the ability to drill into living trees to obtain sap. Because spatial patterns of resource availability influence ...
