Use of Song Types by Male Carolina Chickadees (Poecile carolinensis)
<p>North American chickadees (Poecile spp.) are a closely related group in which vocalizations are very similar. The combinatorial 'chickadee' call, given by all members of the genus, has been well studied, especially in Black-capped chickadees. Chickadee song has received much less study, …

MYCOBIOME ANALYSIS OF TREES SELECTED BY BLACK-CAPPED CHICKADEES (Poecile atricapillus) AS NEST SITES
… of fungi in trees selected by black-capped chickadees (<em>Poecile atricapillus</em>) and compare them to communities in non-selected control trees to determine whether chickadee nest trees are associated with specific fungal taxa and communities. Overall, I identified 201 fungal OTUs to …

SEASONAL CHANGES IN BLACK-CAPPED CHICKADEE (POECILE ATRICAPILLUS) SOCIAL STRUCTURE AND GARGLE VOCALIZATIONS
… can then create local dialects. Black-capped chickadees (<em>Poecile atricapillus</em>) are small songbirds of temperate habitats of North America that group together in larger flocks every winter. Dialects of the gargle vocalization have been identified that differ between chickadee …

Spatial Learning and Memory, Cognitive Flexibility, and Rule-Learning in Food-Caching Mountain Chickadees (Poecile gambeli) Across an Elevational Gradient
… and rule-learning in wild, food-caching mountain chickadees ( Poecile gambeli ). I found that chickadees updated information about their environments more frequently in harsher, less predictable winter environments than in milder, more predictable ones. I showed that chickadees were capable of …

Living in harsh environments: From individuals to social networks
… for survival when resources are scarce. Mountain chickadees are socially monogamous and form stable flocks composed of multiple mated pairs during the nonbreeding season. This presents mountain chickadees with opportunities to learn about their flock mates and potentially maximize the benefits of …

The Causes and Consequences of Complex Behavioral Trait Variation in a Resident Montane Bird
… and nest building, in free-living mountain chickadees ( Poecile gambeli ). Chapter 1 describes the role of directional natural selection acting on spatial cognitive ability using a cohort comparison approach in a wild population. This study showed that spatial cognitive ability does not …

A phylogeographic investigation of the mountain chickadee
Mountain Chickadees (Parus gambeli) were collected from mountain ranges of the Great Basin and surrounding areas. Restriction endonuclease digestion of their mitochondrial DNA revealed two highly distinct haplotypes. One of these occurred in the Great Basin and extended eastward into Arizona and …

Vocalizations influence roost-site selection in overwintering cavity-nesting birds in Eastern Washington
… call treatment for both winters. The presence of chickadees increased following alarm and contact call treatments in 2016-17 and alarm call treatment in 2017-18. The number of black-capped and mountain chickadees increased following the alarm call treatment, and red-breasted nuthatches increased …

Effects of Mid-Rotation Release on Forest Structure, Wildlife Habitat, and Pine Yield
… warblers (Dendroica pinus L.) and black-capped chickadees (Parus atricapillus L.) increased due to reductions in canopy hardwoods and increases in snags. Reduced shrub stratum density resulted in a lower bobwhite quail (Colinus virginianus L.) cover index on imazapyr-released areas.

Relationships Between Winter Energetic Condition and Reproductive Investment in a Wild Bird

Wildlife Response to Stand Structure of Green Ash Woodlands
… field sparrows (Spizella pusilla), black-capped chickadees (Parus atricapillus), American goldfinches (Carduelis tristis), and orange-crowned warblers (Vermivora celata) were found in significantly higher numbers (P 5 .10) in closed stands than in open stands during both 1983 and 1984. A …

The Breeding Biology of the Mountain Chickadee (Parus Gambeli)
The breeding biology of the Mountain Chickadee (Parus gambeli) was studied in 1968, 1969, 1970 in the Robinson Canyon, 13 miles west of Ellensburg, Kittitas County, Washington.
