Introduction
Currently working on Barn owl's movement ecology. Specifically, how they use environmental cues to maximize hunting success, and why females spend large amount of time and flight effort to visit other possible nesting places while raising their current brood. Also, interested and working on soaring bird movements in relation to ecological barriers and atmosphgeric conditions. Furthermore, I study several aspects of shearwaters, lately focused on eco-acoustics methods to monitor their colonies.

Article
Full-text available
Migratory animals are affected by various factors during their journeys, and the study of animal movement by radars has been instrumental in revealing key influences of the environment on flying migrants. Radars enable the simultaneous tracking of many individuals of almost all sizes within the radar range during day and night, and under low visibi...
Article
Full-text available
Studying the causes and consequences of route selection in animal migration is important for understanding the evolution of migratory systems and how they may be affected by environmental factors at various spatial and temporal scales. One key decision during migration is whether to cross “high transport cost” areas, or to circumvent them. Soaring...
Article
Full-text available
Parent-offspring recognition (POR) is fundamental in colonial birds when the potential intermingling of chicks is higher due to the large number and proximity of nests. In species with isolated nests, where chick presence in the nest is strong contextual evidence of kinship, there might be circumstances when the parent might doubt the identity of t...

Flying over the open sea is energetically costly for terrestrial birds. Despite this, over-water journeys of many birds, sometimes hundreds of kilometres long, are uncovered by bio-logging technology. To understand how these birds afford their flights over the open sea, we investigated the role of atmospheric conditions, specifically wind and uplif...
Article
Full-text available
Atmospheric conditions are known to affect flight propensity, behaviour during flight, and migration route in birds. Yet, the effects of fog have only rarely been studied although they could disrupt orientation and hamper flight. Fog could limit the visibility of migrating birds such that they might not be able to detect landmarks that guide them d...

Recent biologging technology helps reveal hidden life and breeding strategies of nocturnal animals. Combining animal trajectories and identified movement patterns with landscape features can reveal meaningful behaviours that directly influence fitness, such as prospecting for nesting sites. Consequently, defining the proximate mechanisms and adapti...

Chapter
The Eurasian sparrowhawk (Accipiter nisus) is a partial migrant, travelling mainly on short to medium distances. It is sedentary in Europe, apart the Scandinavian region, where it is a summer visitor. It migrates using a mixed flight strategy of soaring-gliding and flapping flight modes. It is a fly-andforage migrant, hunting small resident and mig...

The open sea is considered an ecological barrier to terrestrial bird movement. However, over-water journeys of many terrestrial birds, sometimes hundreds of kilometers long, are being uncovered by bio-logging technology. To understand how these birds afford their flights over the open sea, we investigated the role of atmospheric conditions in subsi...

On-line issue: http://www.seabirdgroup.org.uk/seabird-31 We report the finding of an Atlantic Puffin Fratercula arctica on the Mediterranean coast of Israel in September 2018. We use morphometrics and current knowledge of Puffin movements to infer that the bird is likely from the United Kingdom (UK) or Ireland. This record is over 1500 km further...

Human disturbances are increasingly becoming a conservation concern for many populations of colonial seabirds. Colonially reproducing species are particularly vulnerable to localised disturbances because detrimental elements can simultaneously affect the entire population. Studies of petrels and shearwaters have shown that light pollution, in parti...
Article
Full-text available
Billions of migrating birds travel between their breeding and over-wintering areas twice a year, encountering various environmental conditions along their migration routes. Wind is of utmost importance for birds as wind speed and direction may strongly affect the birds’ flight speed and metabolism. Specifically, tailwinds were found to initiate fli...

Weather conditions strongly affect the flight behaviour of birds during migration. Rain or strong headwind may hinder migration by inducing landfalls while the effect of fog on migrating birds has been only rarely described. We analyzed the flight speed and direction of bird tracks collected by surveillance radar at the Strait of Messina, an import...

Billions of migrating birds travel twice a year between their breeding and overwintering areas during which they encounter various environmental conditions. Wind has utmost importance for migrating birds as wind speed and direction may strongly affect the speed and the metabolic rate of flight. Specifically, tailwind assistance (TWA) during migrati...
Thesis
Parent-offspring recognition is well developed in seabird species that breed in colony with high potential of offspring confusion, caused by the proximity of nesting sites and intermingling of chicks. In contrast, parent-offspring recognition is less developed in species that raise a single chick in crevices or holes, such as the Scopoli’s shearwat...
Conference Paper
Full-text available
We investigated body mass variation during the reproductive season in male and female Scopoli's shearwaters (Calonectris diomedea) breeding in Linosa island, Sicily channel. Birds were weighted in three main periods: i.e. before and during egg-laying (mid May - mid June), around hatching (second half of July) and during the early stages of chick re...

Most seabirds are diurnal foragers, but some species may also feed at night. In Peruvian pelicans (Pelecanus thagus), the evidence for nocturnal foraging is sparse and anecdotal. We used GPS-dataloggers on five incubating Peruvian pelicans from Isla Lobos de Tierra, Perú, to examine their nocturnality, foraging movements and activities patterns at...

Project
1) We want to predict nocturnal patterns of colony attendance in relation to moon cycle and light, wind conditions and breeding phase. In order to do so, we will combine radar tracking, passive acoustic monitoring and nest survey. 2) We want to test if the vocal activity can be a good predictor of relative density at the colony. If so we can develop a non-invasive method to use in other similar colonies.
Project
Study and monitoring of the colony of Scopli's shearwaters in Linosa island (Italy), the largest of Europe and the second in the world. This colony is under threat by human activities and disturbance and this species is overall declining. The monitoring started in the 80s under the supervision of the University of Palermo, and now (since 2007) Ornis italica is leading the research on Linosa (on behalf of the UoP).
Project
Shearwaters use shear soaring flying strategy that allow them to fly at huge distance from their colonies with low flight metabolic cost. This type of flight is of particular importance to pelagic seabirds that spend almost their entire lives foraging over the ocean. We will analyse the flight behaviour, the flight-related energy expenditure of more than 60 individuals of Scopoli’s shearwater (Calonectris diomedea) in relation to wind parameters (speed, direction) and the breeding effort (incubation and chick rearing phase).
