Smaller owls and hawks are high-threat predators to small songbirds, like chickadees, in comparison to larger avian predators due to smaller raptors’ agility (Templeton et al. in Proc Natl Acad Sci 104:5479–5482, 2005). The current literature focuses only on high- and low-threat predators. We...

Sex differences have been identified in a number of black-capped chickadee vocalizations and in the chick-a-dee calls of other chickadee species [i.e., Carolina chickadees (Poecile carolinensis)]. In the current study, 12 acoustic features in black-capped chickadee chick-a-dee calls were...

In a two-stimulus visual discrimination choice task with a reversal in reward contingencies midway through each session, pigeons produce a surprising number of anticipatory errors (i.e., responding to the second-correct stimulus before the reversal) based on failure to inhibit timing-based...

The songs of many songbird species vary geographically, yet, the songs of black-capped chickadees (Poecile atricapillus) show remarkable consistency across most of the species’ North American range. Previous research has described subtle variations in the song of this species by comparing songs...

This study contrasted two hypotheses theorizing the role of the global shape of a boundary in object location memory. People differentiate reference points based on the global shape extracted from the environment configuration and choose appropriate parts for encoding a specific location....

Three experiments using a spelling error detection task, in which participants were asked to determine whether words have a spelling error, investigated the extent to which morphemes and pseudo-morphemes affect word processing. We compared the processing of transparent compound words (e.g.,...

Chickadees produce many vocalizations, including chick-a-dee calls which they use as a mobbing call in the presence of predators. Previous research has shown that chickadees produce more D notes in their mobbing calls in response to high-threat predators compared to low-threat predators, and may...

Chickadees are high-metabolism, non-migratory birds, and thus an especially interesting model for studying how animals follow patterns of food availability over time. Here, we studied whether black-capped chickadees (Poecile atricapillus) could learn to reverse their behavior and/or to anticipate...

This study investigated when the Bayesian cue combination of piloting and path integration occurs in human homing behaviors. The Bayesian cue combination was hypothesized to occur in estimating the home location or self-localization. In Experiment 1, the participants learned the locations of five...

Two experiments investigated how people use buildings and street configurations to reorient in large-scale environments. In immersive virtual environments, participants learned objects’ locations in an intersection consisting of four streets. The objects’ locations were specified by two cues: a...
