Spatiotemporal Dynamics of Blood Parasite Infections and Impacts on Avian Health and Reproduction

Molecular Ecology, Volume 34, Issue 24, December 2025.
ABSTRACT Parasitic infections are ubiquitous in nature, but their consequences are often difficult to evaluate in wildlife. This is particularly the case for chronic infections for which fitness impacts can be subtle or confounded with other intrinsic and extrinsic factors.

Prevalence of new and known species of haemoparasites in feral pigeons in northwest Italy [PDF]

, 2015
Background: Haemoparasites in feral pigeons have been studied in several countries but no data are available from Italy. The aim of this work was to evaluate the prevalence and diversity of Haemoproteus spp./Plasmodium spp. and Leucocytozoon spp.

Subtle stressors—Strong responses. Consistent negative effects of avian blood parasites on phenotypic and demographic traits across songbirds

Journal of Animal Ecology, Volume 94, Issue 10, Page 1908-1921, October 2025.
Avian blood parasites are widespread and often considered benign, yet mounting evidence suggests they subtly impair host traits. This meta‐analysis is timely and necessary to quantify their true impact across systems, challenging assumptions and highlighting overlooked consequences for fitness and population dynamics. Abstract Stressors that subtly yet

Molecular probes for the identification of avian Haemoproteus and Leucocytozoon parasites in tissue sections by chromogenic in situ hybridization

Parasites & Vectors, 2019
Background Avian haemosporidian parasites can cause severe disease in their hosts due to excessive exo-erythrocytic merogony and anaemia caused by blood stages.

Análise de Haemoproteus em pomba

Brazilian Journal of Animal and Environmental Research
Este relatório descreve o caso de uma pomba (Columba livia) diagnosticada com o hemoparasita Haemoproteus, identificado por meio de um hemograma. O Haemoproteus é transmitido por insetos hematófagos, como a "mosca do pombo" (Pseudolynchia canariensis), e, embora geralmente causa poucos sintomas, pode levar a problemas mais graves, como anemia e perda ...

Reduced Offspring Viability Is Associated With Long‐Term Stability of a Narrow Avian Hybrid Zone

Ecology and Evolution, Volume 15, Issue 9, September 2025.
We investigated hybrid viability in a tropical, avian hybrid zone governed by strong selection on male secondary sexual traits between the white‐collared manakin (Manacus candei) and golden‐collared manakin (M. vitellinus). We assessed putative hybrid fitness by investigating adult survival and hatching success along with a prospective selective ...

Hematozoa of Common Grackles (Quiscalus quiscula versicolor, Vieillot) in Central Arkansas [PDF]

, 1990
During the years 1977-84, 118 bronzed grackles, Quiscalus quiscula versicolor, Vieillot, of 132 examined were found infected with hematozoa. The eight species of symbionts collected from the infected birds included two microfilarial species (Chandlerella
