No evidence for associations between brood size, gut microbiome diversity and survival in great tit (Parus major) nestlings
BackgroundThe gut microbiome forms at an early stage, yet data on the environmental factors influencing the development of wild avian microbiomes is...

Variation in the use of anthropogenic materials in tit nests: influence of human activities and pandemic restrictions
As urbanization expands, so does the presence of anthropogenic materials within bird’s nests. However, our understanding of this phenomenon remains...

Relations between the Leukocyte Profile and the Energy State, Hematocrit, and Blood Metabolites in the Great Tit (Parus major)
AbstractThe health of animal populations can reflect ongoing changes in their environment. Various physiological parameters can be used to assess...

Nest structure and breeding success in two tit species: a long-term study
One of the most critical functions of nests in parids is thermal insulation, particularly during egg incubation by females and during the first week...

Prehatching temperatures drive inter-annual cohort differences in great tit metabolism
Basal metabolic rate (BMR) constitutes the lowest metabolic rate in a resting animal and is, therefore, considered to reflect the energetic cost of...

The effect of daylight exposure on the immune response and body condition of Great Tit nestlings
Natural light plays an important role in many aspects of birds’ biology, ecology and behaviour. Wild birds experience various light conditions, both...

Nest size parameters of Great Tits and Blue Tits: a long-term study
Nest construction behaviour is widespread among bird species. Causes for the occurrence and great variation in nest characteristics between and...

No evidence that nest site choice in Pied Flycatchers is mediated by assessing the clutch size of a heterospecific, the Great Tit
Among species that use similar resources, an individual may benefit by observing and copying the behavioural decision of a heterospecific. We tested...

Great and blue tit laying dates vary with fine-scale variation in local tree composition but not tree budburst
Many studies have investigated how spring temperature affects laying dates and how this in turn affects the synchrony between nestling food demands...

Is there a role for aromatic plants in blue tit (Cyanistes caeruleus) nests? Results from a correlational and an experimental study
AbstractThe utility of fresh green material in avian nests is still not fully understood. Potential explanations include the effects of plants’...

Effects of an extreme weather event over reproduction and survival of Great Tits (Parus major) in eastern Spain
The frequency of extreme climatic and weather events has increased since 1950 due to global changes induced by human influence. These events can have...

Breeding biology of the Green-backed Tit (Parus monticolus) in southwest China
Studies on breeding biology enable us to broaden our understanding of the evolution of life history strategies. We studied the breeding biology of...

An avian urban morphotype: how the city environment shapes great tit morphology at different life stages
Urbanization is a worldwide phenomenon associated with tremendous modifications of natural habitats. Understanding how city dwelling species are...

Season does not influence the response of great tits (Parus major) to allopatric mobbing calls
Many species of birds emit mobbing calls to recruit prey to join mobbing events. This anti-predator strategy often involves several species and,...

Experimental evidence that adult UV/yellow colouration functions as a signal in blue tit families — but only for parents
AbstractIn bi-parental species, reproduction is not only a crucial life-history stage where individuals must take fitness-related decisions, but...

Effects of competition and predation operating at individual and population levels: an overview of results from a long-term field experiment
After an overview of the discussion about the existence of intra- and interspecific competition that illustrates the contradictory opinions I...
-
Great tit responses to the calls of an unfamiliar species suggest conserved perception of call ordering
AbstractMany species of birds produce distinct calls when mobbing predators. These calls often recruit nearby conspecifics and heterospecifics to...

Sex and Age Determination of the Eurasian Coal Tit (Periparus ater, Passeriformes, Paridae) Using Anatomical and Morphological Characteristics of the Wing
AbstractVirtually no studies have been carried out involving cases of mass bird mortality, although this is a unique opportunity to conduct...

Weather, food and predation shape the timing of Marsh Tit breeding in primaeval conditions: a long-term study
Marsh Tits Poecile palustris were studied in primaeval fragments of Białowieża National Park (Poland) between 1997 and 2020 to investigate how...

Winter food selection and exploratory behavior vary with natal territory characteristics in wild great tits
AbstractDifferences in habitat characteristics experienced during rearing associate with variation in a range of behavioral phenotypes such as...
