A feeding experiment on migratory fuelling in whitethroats, Sylvia communis
Article Abstract:
A feeding experiment on the island of Gotland in the Baltic region was conducted to examine the impact of food abundance on the behavior of whitethroats when preparing for autumn migration. A higher level of body mass was attained by whitethroats attracted to a feeding site than birds in natural conditions. The average rate of fuel deposition and departure fuel load were higher for birds at a feeding site than for birds in natural conditions. However, a lack of correlation was found between rate of fuel deposition and departure fuel load.

Light-induced migration behaviour of Daphinia modified by food and predator kairomones
Article Abstract:
Food availability for Daphnia, lake-dwelling waterfleas, is highest near the surface of the water, but predation is also most severed. Daphnia were tested to determine whether they process information derived from food and predator presence to estimate migration costs and benefits. Downward swimming of daphnia galeataxhyalina was studied in response to increases intensity of light at food and fish kairomone concentrations. Each had a modifying, additive, but independent effect.
