Only detailed (e.g. satellite) tracking of individual migrants can reveal the rel...

متن کاملSocial Dominance and Energy Reserves in Wintering Woodland Birds’ Vladimir
To understand animals’ tactics for surviving the winter season, we need to know how they manage their energy reserves. Fat reserves in small birds in winter generally increase with starvation risk. Studies have documented higher fat reserves in response to various sources of variability in energy intake or expenditure. Using three woodland species, Carolina Chickadee (Poecile carolinensis), Tuf...
