Eight radio-tagged Alpine Choughs were tracked around Cervinia (Aosta, Italy) in summer 1989 and 1990. Range size varied from 7.1 to 16.7 km2. All of the birds used both alpine meadows and high mountain cliffs but spent on average only 10 % of their foraging time around human developments. Two of the birds in 1989 made regular journeys between meadows and cliffs, taking on average 15.1 min for the journey, spending 24–29 min on the cliffs, 2.9 min on the return crossing and 36–41 min foraging… 
Behavioural responses to human disturbance in an alpine bird
TLDR
It was found that human presence was negatively associated with intake rates and amount of time spent in a foraging patch (‘stay time’), and that the effects could be both positive and negative.
The impact of high-altitude ski pistes on ground-dwelling arthropods in the Alps
TLDR
Concerns over the possible disruption of local ecosystem functionality and over the conservation of arthropod species which are endemic to restricted alpine areas are supported.
Corvids in Urban Environments: A Systematic Global Literature Review
TLDR
A review of the global literature on the effects of urbanization on species of family Corvidae indicates that corvids show both flexibility in resource use and behavioral plasticity that enable them to exploit novel resources for nesting and feeding.

Foraging behaviour and diet of the Alpine ChoughPyrrhocorax graculus in the Italian Alps in summer
TLDR
The Choughs' very short stay time in any one patch of meadow is consistent with their high intake rates and apparently low costs of movement between feeding sites, but they may also be sampling in a highly variable environment.
