Background The Major Histocompatibility Complex (MHC) plays a central role in immunity and has been given considerable attention by evolutionary ecologists due to its associations with fitness-related traits.

Sparrow Preferences for Winter Cover Crops in California's Central Coast
Agriculture in many regions of the world has reduced bird habitat and abundance, and altered avian community structure. A study was conducted on an organic research farm over two winters (Oct to Mar) in an intensive agricultural region of Salinas Valley,

Avian Malaria Among House Sparrows: a Survey of Disease and Mosquito Vectors (Diptera: Culicidae) in Reed City, Michigan [PDF]
Nine of 350 house sparrows caught in Reed City, Michigan, had malaria parasites detectable on Giemsa-stained thin films. All of the infected birds were juveniles, Parasitemias were too low to permit identification of the Plasmodium present. Collection of

Species with similar ecological characters often compete with each other; however, a species may also facilitate the survival or reproduction of another ecologically similar species, although such interaction is rarely documented in birds.

The extent to which animal societies exhibit social conformity as opposed to behavioural diversity is commonly attributed to adaptive learning strategies. Less attention is given to the possibility that the relative difficulty of learning a task socially

Fine-scale population structure and asymmetrical dispersal in an obligate salt-marsh passerine, the Saltmarsh Sparrow (Ammodramus Caudacutus) [PDF]
Understanding the spatial scale of gene flow can yield valuable insight into the ecology of an organism and guide conservation strategies. Fine-scale genetic structure is uncommon in migratory passerines because of their high vagility and presumed high ...

Characterization of mercury and its risk in Nelson's, Saltmarsh, and Seaside Sparrows. [PDF]
BACKGROUND: Nelson's, Saltmarsh, and Seaside Sparrows (Ammodramus nelsoni, A. caudacutus, and A. maritimus, respectively) depend on marsh and wetland habitats--ecosystems in which mercury (Hg) bioavailability is notoriously high.

Supplementary feeding increases nestling feather corticosterone early in the breeding season in house sparrows [PDF]
Several studies on birds have proposed that a lack of invertebrate prey in urbanized areas could be the main cause for generally lower levels of breeding success compared to rural habitats.

Differential introgression and the maintenance of species boundaries in an advanced generation avian hybrid zone [PDF]
Background: Evolutionary processes, including selection and differential fitness, shape the introgression of genetic material across a hybrid zone, resulting in the exchange of some genes but not others.
