Abstract. Avian foraging activity during daytime peaks after dawn and before dusk. The relative importance of each period of intensive foraging on the accumulated intake varies by species, individual, and day. We studied the relative importance of each period from direct observation of radio-tagged Common Cranes (Grus grus) during winter at a site of stopover and wintering in Spain. After a mathematical model was fitted, accumulated intake showed a typical anti-sigmoid shape, with greatest… 
Food Availability But Not Sex Determines Morning Foraging Area Size in the Great Bustard Otis tarda, the Most Sexually Size-Dimorphic Bird Species
TLDR
Results obtained from a short-term study of foraging area size in the Great Bustard Otis tarda do not preclude an effect of sexual size dimorphism on MFA size and FI of Great Bustards over longer periods but show that the body size effect on foraging behaviour may be smaller than predicted only by SSD.
The potential impacts of changes in ecological networks, land use and climate on the Eurasian crane population in Estonia
AbstractContextThe Eurasian crane (Grus grus) is an iconic and sensitive species. It is therefore necessary to understand its landscape ecology in order to determine threats. Objectives(1) To map the

DAILY ACTIVITY AND INTAKE RATE PATTERNS OF WINTERING COMMON CRANES Grus grus
Daily activity patterns ofwintering CommonCranes Crusgrus were studied at Gallocanta, NE Spain, and related with changes in foraging site, distance to roost and flocking behaviour. Per cent time
Dominance and the dynamics of phenotype-limited distribution in common cranes
TLDR
The results suggest that the dynamics that led to a truncated phenotype-limited distribution were determined by social dominance and food abundance, with dominant cranes shifting to a new zone to maintain their high intake levels and subordinates changing more frequently whenever their daily intake did not reach the minimum metabolic requirements.
Avian daily foraging patterns: Effects of digestive constraints and variability
TLDR
It is suggested that the characteristic daily feeding pattern of small birds is not due to digestive constraints but is greatly influenced by environmental variability.
Age-related differences in time budgets and parental care in wintering common cranes
ABsTRcT.-We compared the behavior and food intake rate of parent, nonparent and juvenile wintering Common Cranes (Grus grus) to evaluate possible costs and benefits resulting from parental care. Time
A Search for Environmental Cues Used by Birds in Survival of Cold Winters
Winter can offer an assortment of difficulties for passerines and other small terrestrial birds (body mass: <100g, and in many instances <25 g) that reside in continental climates at higher
Length of feeding day and body weight of great tits in a single- and a two-predator environment

TLDR
The presence of the two predators increases unpredictability in feeding conditions for great tits by shortening their feeding day and increasing body reserves at dusk, and dominants carried significantly greater reserves than subordinates in the area inhabited by two predators.
Foraging routines of small birds in winter: a theoretical investigation
We investigate the way in which the opposing forces of starvation and predation combine to influence daily foraging routines in populations of small, wintering birds. To avoid starvation in an
Strategic Regulation of Body Mass and Singing Behavior in New Zealand Robins
TLDR
The results suggest that potentially energetically costly behaviors, such as song production, are sensitive to short-term changes in energy reserves, and that both state and behavioral predictions can be successfully integrated to provide tests of state-based models of behavior.
