Development and validation of a house finch interleukin-1β (HfIL-1β) ELISA system [PDF]
BMC Veterinary Research, 2017 Background A unique clade of the bacterium Mycoplasma gallisepticum (MG), which causes chronic respiratory disease in poultry, has resulted in annual epidemics of conjunctivitis in North American house finches since the 1990s.

Differing House Finch Cytokine Expression Responses to Original and Evolved Isolates of Mycoplasma gallisepticum [PDF]
Frontiers in Immunology, 2018 The recent emergence of the poultry bacterial pathogen Mycoplasma gallisepticum (MG) in free-living house finches (Haemorhous mexicanus), which causes mycoplasmal conjunctivitis in this passerine bird species, resulted in a rapid coevolutionary arms-race

Response of black-capped chickadees to house finch Mycoplasma gallisepticum. [PDF]
PLoS ONE, 2015 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

Language-like efficiency and structure in house finch song. [PDF]
Proc Biol Sci, 2023 Communication needs to be complex enough to be functional while minimizing learning and production costs. Recent work suggests that the vocalizations and gestures of some songbirds, cetaceans and great apes may conform to linguistic laws that reflect this trade-off between efficiency and complexity.

Varying conjunctival immune response adaptations of house finch populations to a rapidly evolving bacterial pathogen [PDF]
Frontiers in ImmunologyPathogen adaptations during host-pathogen co-evolution can cause the host balance between immunity and immunopathology to rapidly shift. However, little is known in natural disease systems about the immunological pathways optimised through the trade-off ...

A house finch (Haemorhous mexicanus) spleen transcriptome reveals intra- and interspecific patterns of gene expression, alternative splicing and genetic diversity in passerines. [PDF]
BMC Genomics, 2014 Background: With its plumage color dimorphism and unique history in North America, including a recent population expansion and an epizootic of Mycoplasma gallisepticum (MG), the house finch (Haemorhous mexicanus) is a model species for studying sexual ...

Plumage redness signals mitochondrial function in the house finch. [PDF]
Proc Biol Sci, 2019 AbstractCarotenoid coloration is widely recognized as a signal of individual condition in various animals, but despite decades of study, the mechanisms that link carotenoid coloration to condition remain unresolved. Most birds with red feathers convert yellow dietary carotenoids to red carotenoids in an oxidation process requiring the gene encoding the

Florida's Introduced Birds: House Finch (Carpodacus mexicanus)
EDIS, 2009 WEC-253, a 5-page illustrated fact sheet by Steve A. Johnson and Jill Sox, introduces this small, seed-eating songbird native to the southwestern United States, but whose range has extended to northern parts of Florida since the 1950s.

In sickness and in health: group-living augments behavioural responses to food and predation risk for sick house finches (Haemorhous mexicanus) [PDF]
Royal Society Open ScienceGroup-living provides many fitness benefits for individual members, including improved foraging and predator vigilance. If such benefits are especially pronounced for sick members, group-living can act as a form of behavioural tolerance by offsetting ...

Cis‐regulatory sequence variation and association with Mycoplasma load in natural populations of the house finch (Carpodacus mexicanus) [PDF]
Ecology and Evolution, 2013 Characterization of the genetic basis of fitness traits in natural populations is important for understanding how organisms adapt to the changing environment and to novel events, such as epizootics.
