Pitch-related cues in the songs of sympatric mountain and black-capped chickadees.
Acoustic frequency (pitch) cues are known to be important in the recognition of conspecific song in a number of songbird species. Mountain chickadees (Poecile gambeli) and black-capped chickadees (Poecile atricapillus) are sympatric over parts of their ranges and their species-typical songs share many features. I examined the acoustic characteristics of song of these two congeners in a region o...
متن کاملResponse of Black-Capped Chickadees to House Finch Mycoplasma gallisepticum
Tests for the presence of pathogen DNA or antibodies are routinely used to survey for current or past infections. In diseases that emerge following a host jump estimates of infection rate might be under- or overestimated. We here examine whether observed rates of infection are biased for a non-focal host species in a model system. The bacterium Mycoplasma gallisepticum is a widespread pathogen ...
متن کاملMechanisms of what-where-when memory in black-capped chickadees (Poecile atricapillus): do chickadees remember "when"?
Integrated what-where-when memory, sometimes called 'episodic-like' memory, has been shown to occur in a number of animals, including food-storing birds and rodents. It is not always clear in these studies, however, what aspect of "when" is remembered. We examined memory for what, where, and when in black-capped chickadees Poecile atricapillus in a procedure designed to dissociate memory for el...
متن کاملMobbing Calls of Black-Capped Chickadees: Effects of Urgency on Call Production
-Many animals advertise the presence of a predator threat through vocal signals. Black-capped Chickadees (Poecile atricapilla) use their chick-a-dee call as a mobbing call when encountering a perched hawk or owl. This social signal appears to serve as an alert to other chickadees, causing them to rally to the vicinity of the predator and join in a chorus of calling. We asked the question: do ch...
متن کاملImpact of Tent Caterpillar Defoliation on the Reproductive Success of Black-capped Chickadees’
Outbreaks of folivorous Lepidoptera caterpillars are common in temperate forests (Ives and Wong 1988, Butterworth 1990). The high fat content, low chitin content, and large size of these larvae make them an important component of the diet of many temperate birds (Betts 1955, Robinson and Holmes 1982, Holmes and Schultz 1988, Sample et. al. 1993). Outbreaks of most species should increase availa...
