Opis:
Prevalence of flea infestation in nests of Blue Tit Parus caeruleus was analyzed and compared with these of other hole-nesting birds. Nests were collected from nestboxes prior to youngs fledging. It was found that prevalence of fleas was very low in comparison to other studies of Blue Tits nests and to other bird species. The possible reasons of this low prevalence are discussed.

Like many other seasonally breeding birds, Blue Tits raise their chicks mainly at the time when numerous caterpillars attack fresh oak leaves. This paper reports on the results of the first quantitative study of food ecology in combination with the breeding biology of a North African population of Blue Tits occupying distinct patches of oak habitat (high-altitude semi-evergreen zeen oak versus low-altitude evergreen cork oak). To check for between-habitat differences in intensities of nest parasites feeding on chicks, all nests monitored were heat-treated during the chickraising stage. The peak demands of the chicks were found to coincide with the peak date of caterpillar availability in both habitat types. Food availability was much higher in the semi-evergreen habitat, and the diversity of prey delivered to the chicks was higher in the evergreen habitat. Surprisingly, breeding success was very low in both habitat types. It is suggested that several environmental constraints may cause maladapted avian breeding responses in heterogeneous Algerian habitat mosaics. Spatial variation in micro-climate may influence the capacity to adaptively adjust breeding responses to distinct habitat types.

Arthropod assemblages living in tree canopies in two habitat types — a rich woodland and poor parkland were studied in 2003–2005 as a background for describing the dynamics of caterpillars; the study system was located in central Poland. Caterpillars, the optimal food of breeding tits, varied in abundance between both habitats and years. The peak abundance of caterpillars was at least 3 times higher in the woodland than in the parkland habitat. There were also pronounced differences in caterpillar production between years, with every consecutive year during 2003–2005 being trophically worse than the previous one. The Blue Tits' timing of breeding coincided roughly with the timing of caterpillar abundance in particular years. Mean clutch size corresponded strictly to the inter-habitat and inter-year pattern of variation in caterpillar availability, suggesting adaptive responses in Blue Tit reproduction to food resources.

The influence of a parasite (larvae of Protocalliphora, Diptera: Calliphoridae) on an avian host (Blue Tit) was studied in 1994–1997 as part of a long-term research project on a population of Blue Tits inhabiting nest boxes on the island of Corsica. The Blue Tit broods were heavily infested with Protocalliphora larvae. The abundance of caterpillars as a key food type for the tits was monitored. A random sample of 16 nests was experimentally subjected to an anti-parasite heat treatment, which resulted in a marked decline in the numbers of Protocalliphora larvae. Untreated nests, with high numbers of parasites, were regarded as control nests. Under the anti-parasite treatment, Blue Tit nestlings were fed less frequently than the control nestlings (8 v. 11 food items per hour per nestling). Significant changes in the diet composition occurred, with parasite-free nestlings being consistently fed with fewer caterpillars. An average parasitised nestling was supplied by its parents with 2.6 caterpillars more than an average parasite-free chick. This suggests that in the highly parasitised control nests, the parent tits made an effort to compensate for the detrimental effects caused by Protocalliphora larvae. Feeding rate and food composition were shown to influence chick condition and survival in the nest. In spite of these facts, the nestlings in parasitised nests developed less rapidly and had lower survival rates than in the anti-parasitically heat-treated nests. The parasitic Protocalliphora larvae have a double effect on their avian host: they adversely affect nestling performance, and they compel adult tits to work harder in order to at least partially compensate for that influence.

Abstract in Polish. Taxa in Latin
Some models of central place foraging relate the time taken to deliver a prey to the selectivity of the forager. If birds have to travel longer, they are expected to take only larger prey. Prey selectivity may also increase if birds have more time available for search activities. I tested this last hypothesis by experimentally increasing the food available to Blue Tits during young rearing. Insect larvae were offered to breeding adults from egg hatching to fledging of the young. Provisioning rates and prey size were studied by videotaping. In experimentally overfed broods, part of the additional food was delivered to their nestlings by the adults, while the rate of feeding with natural prey decreased compared to unmanipulated pairs. Overfed males delivered larger insect larvae than control males, while females showed no response to the treatment. Overfed males could deliver larger prey at late chick ages (when presumably the chicks' demand is higher) than controls, suggesting that control males were time- (or energy) constrained. Moreover, overfed parents appeared to choose relatively more prey that may be important in the chicks' diet. The results show that prey selectivity is related to time (or energy) budgets.

Opis:
We investigated whether high−intensity road traffic affects the nestbox occupancy pattern of secondary hole−nesting birds. Field studies were carried out in two forests in south−eastern Poland (Lasy Janowskie forest and Polichna forest). Both complexes were included in NATURA 2000 network. In our knowledge it was first field experiment on road−traffic noise influence on forest birds, conducted in the Polish environmental conditions. The results of this experiment can be used in work on the impact of road projects on forest birds. Nestboxes were hung at twelve linear transects located perpendicularly to the busy road and they were regularly inspected in 2011−2012. Road noise was measured by use of a digital measurer of sound level at each nestbox. Monitoring the activity of predators on the study area was done with the help of digital trail cameras and experiment with use of artificial nest with eggs. Noise level decreased with distance from the road. In the first year of experiment we observed that the birds settled preferentially habitats in the vicinity of road. However in next season the number of occupied nestboxes was independent from the distance from road. We found that the pressure caused by predators on the study area was very low, creating safer nesting places for birds. Our results provide evidence that these birds are well adapted to cope with anthropogenic noise. Some species of birds preferred nesting in neighbourhood of road.
