Factors influencing double brooding in Eurasian Hoopoes Upupa epops [PDF]

open access: yes, 2015
Double brooding may be a good strategy for short-lived species to maximize annual and lifetime reproductive success (ARS and LRS, respectively). Nevertheless, there is typically individual variation in the probability of producing a second clutch.

Year-round tracking of small trans-Saharan migrants using light-level geolocators. [PDF]

open access: yesPLoS ONE, 2010
Since 1899 ringing (or banding) remained the most important source of information about migration routes, stopover sites and wintering grounds for birds that are too small to carry satellite-based tracking systems. Despite the large quantity of migrating

Diverse migration strategies in hoopoes (Upupa epops) lead to weak spatial but strong temporal connectivity [PDF]

open access: yes, 2018
The annual cycle of migrating birds is shaped by their seasonal movements between breeding and non-breeding sites. Studying how migratory populations are linked throughout the annual cycle—migratory connectivity, is crucial to understanding the ...

An experimental test of host's life history traits modulation in response to cuckoo parasitism risk. [PDF]

open access: yesPLoS ONE, 2017
Hosts can counteract parasites through defences based on resistance and/or tolerance. The mechanistic basis of tolerance, which involve defensive mechanisms minimizing parasite damage after a successful parasitic attack, remains poorly explored in the ...

Breeding record of Common Hoopoe Upupa epops (Aves: Upupidae) at Satchari National Park in northeastern Bangladesh

open access: yesJournal of Threatened Taxa, 2019
Common Hoopoe Upupa epops was thought to breed in Bangladesh but with no confirmed records.  The observation presented in this paper of a breeding pair with its chick at Satchari National Park in northeastern Bangladesh is the first confirmed breeding ...

Territory occupancy and parental quality as proxies for spatial prioritization of conservation areas. [PDF]

open access: yesPLoS ONE, 2014
In order to maximize their fitness, individuals aim at choosing territories offering the most appropriate combination of resources. As population size fluctuates in time, the frequency of breeding territory occupancy reflects territory quality.

Effect of pinetree thinning and of undergrowth control on the bird community in a Mediterranean coastal pinewood (Castel Fusano, Rome, C Italy).

open access: yesRivista Italiana di Ornitologia - Research in Ornithology, 2012
The authors studied for six years the effects of tree thinning and of undergrowth control in a coastal pinewood of Central Italy. The changes induced by cultivation activities have caused a significant contraction of richness abundance and diversity, not
