Egg covering in cavity nesting birds may prevent nest usurpation by other species
Some birds cover their eggs with nest material when they leave to forage. It has been suggested that such egg-covering aids thermoregulation or prevents predation but here we present a new hypothesis, that secondary cavity-nesting species cover their eggs to prevent nest usurpation by other birds. When the bottom of the cavity is dark, as when eggs are covered by nest material, it may be difficult for a prospecting competitor to see whether a defending nest owner or a predator is hiding inside the cavity. Competitors may therefore hesitate to enter dark cavities. We filmed 21 great tit (Parus major) nests during the egg-laying period and found that the female spent bouts of highly variable length outside the nest box (range 0.3–250 min, n = 51), so prospecting small passerines would have difficulty predicting whether an aggressive tit owner was in the box or would soon return. We presented prospecting male pied flycatchers (Ficedula hypoleuca) with a dyad of boxes (n = 93), each containing a great tit nest but only one with visible eggs. Flycatchers hesitated more to enter a nest box with no visible tit eggs than a box with exposed eggs. This was most evident for nest boxes with dark versus light interior paint, supporting the idea that better interior illumination makes prospecting birds more confident about entering an unfamiliar cavity. The usurpation and predation hypotheses are not mutually exclusive because both competitors and small predators may hesitate to enter dark, enclosed spaces if visibility is low.

Nests of Wrens (Troglodytes troglodytes) in man-made structures and in nests of Barn Swallow (Hirundo rustica) and Dipper (Cinclus cinclus)
The breeding biology of the Wren (Troglodytes troglodytes) nesting inside buildings (54 nests) and beneath river bridges (44 nests) and using disused nests of Barn Swallow (Hirundo rustica) (37) and Dipper (Cinclus cinclus) (8) was studied. Most clutches were initiated in May (67 %), and consisted of five eggs with an overall mean of 5.1. Clutches initiated in April and May were larger (mean = 5.2) than clutches initiated in June and July (mean = 4.7), and larger clutches produced proportionately larger numbers of young. The overall success of 35 nests was 70.6 %.

Variation in population size, nest distribution, colony extent, and timing of movements at the largest known parrot colony
Psittaciformes are among the most threatened birds, and population size and trend estimates are needed to aid conservation. The burrowing parrot Cyanoliseus patagonus is undergoing substantial changes in its population size, due to habitat degradation, trapping for the pet trade, and persecution as crop pest. The species formerly had several large colonies, but these were severely reduced during a programme of agricultural pest control. Currently, only one large colony remains, together with a decreasing number of smaller colonies spread throughout the Monte and adjacent ecoregions. The colony at El Cóndor, north‐eastern Patagonia, Argentina, is of particular importance, concentrating 71% of the global breeding population of burrowing parrots. We aimed to determine changes in 1) breeding population size, 2) the extent of the colony, 3) the distribution of nests along the colony, and 4) the timing of movements from the nest to the foraging locations during the breeding season, over our long‐term study (1998–2019). We found that the number of active nests declined from 37 531 in 2001 to 21 883 in 2005, and recovered in the following years, reaching 40 671 nests in 2019. The decline observed in 2005 could be related to droughts and associated food shortage during the La Niña phase of El Niño Southern Oscillation. The colony expanded westwards, from 9 km length in 2001, to 18.1 km in 2019. During the same period, the part of the colony with the highest number of active nests shifted 5 km westwards from El Cóndor village. Both changes could be the consequence of human disturbance. As any serious threat affecting this colony could have severe consequences for the survival of the species, regular monitoring is needed, together with legal protection of the burrowing parrot colony at El Cóndor and the Monte ecosystem around it.

Using radio frequency identification (RFID) technology to characterize nest site selection in wild Japanese tits Parus minor
Selecting a suitable nest site is critical to the survival and reproduction of birds. Prospecting allows individuals to gather information on the local quality of potential future breeding sites, which may help them make the best nest site selection decision. However, few studies have focused on the direct links between the prospecting activity of breeders and subsequent nest site selection. In this study, we investigated the prospecting pattern of Japanese tits Parus minor during the pre‐breeding period of the first breeding attempt and whether nest site characteristics influence their nest box visiting behaviour and occupied nest site. We used radio frequency identification (RFID) to track the movements of Japanese tits visiting nest boxes and compared nest site characteristics between visited and unvisited (control) nest boxes, as well as between visited and occupied nest boxes. We found that Japanese tits started visiting nest boxes approximately 20 days before breeding, visited an average of six nest boxes and eventually chose the most visited nest box for breeding activities. Japanese tits were more likely to visit nest boxes that had less canopy cover and lower shrub density but a greater total number of surrounding trees and ultimately chose breeding nest boxes with a smaller entrance inclination, in nesting trees with a larger diameter at breast height (DBH) which were surrounded by trees with a larger DBH. Our results suggest that Japanese tits visit several potential breeding sites before choosing breeding nest boxes and that nest site characteristics can influence their prospecting activity and nest site selection.
