Low prevalence of blood parasites in a long-distance migratory raptor: the importance of host habitat [PDF]

, 2015
Background: The low prevalence of blood parasites in some bird species may be related to the habitats they frequent, the inexistence of the right host-parasite assemblage or the immunological capacity of the host.

Bird Community Composition, Migration, and Environmental Factors Jointly Influence the Global Distribution of Avian Haemosporidian Lineages

Integrative Zoology, Volume 21, Issue 1, Page 60-68, January 2026.
Avian haemosporidians are widely distributed; however, the role of migratory and non‐migratory birds, as well as environmental conditions, is incompletely understood. A histogram of the number of parasite lineages per ecoregion shows the variation in avian haemosporidian richness across space.

Co- and mixed-infections of avian haemosporidian parasites in great tits and blue tits of the French Pyrenees [PDF]

, 2018
Avian haemosporidia have played a significant role in advancing our understanding of vectored disease epidemiology, and continue to do so. These diverse blood parasites (inclusive of those responsible for avian malaria) are globally distributed, adopt ...

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

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

Does haemosporidian infection affect hematological and biochemical profiles of the endangered Black-fronted piping-guan (Aburria jacutinga)? [PDF]

, 2013
Infectious diseases can cause deleterious effects on bird species, leading to population decline and extinction. Haemosporidia can be recognized by their negative effects on host fitness, including reproductive success and immune responses. In captivity,

Malaria parasites and related haemosporidians cause mortality in cranes: a study on the parasites diversity, prevalence and distribution in Beijing Zoo

Malaria Journal, 2018
Background Malaria parasites and related haemosporidian parasites are widespread and may cause severe diseases in birds. These pathogens should be considered in projects aiming breeding of birds for purposes of sustained ex situ conservation.

Complex interactions between bacteria and haemosporidia in coinfected hosts: An experiment

Ecology and Evolution, 2020
Hosts are typically coinfected by multiple parasite species whose interactions might be synergetic or antagonistic, producing unpredictable physiological and pathological impacts on the host. This study shows the interaction between Plasmodium spp.

First case report of mortality in an egg‐incubating boreal owl (Aegolius funereus) due to combined Yersinia pseudotuberculosis and Sarcocystis spp. infections

Veterinary Record Case Reports, Volume 13, Issue 3, September 2025.
Abstract Records of lethal consequences from bacterial and parasitic infections in wildlife are scarce, and the conditions under which pathogens cause mortality in infected animals remain poorly understood. We report the first documented case of a female boreal owl (Aegolius funereus) incubating eggs that died on the nest due to a co‐infection with ...
