Data set for «Short- and long-distance avian migrants differ in exercise endurance but not aerobic capacity"

Data set of body condition parameters and aerobic metabolic performances of four Old-world flycatcher species (Muscicapidae) during spring migration. The species differ in their migration strategies: European robins (Erithacus rubecula) and black redstarts (Phoenicurus ochruros) are short-distance migrants spending their entire annual cycle within the Palaearctic and some populations move from North African non-breeding grounds to breeding sites in continental Europe. In contrast, common redstarts (P. phoenicurus) and whinchats (Saxicola rubetra) are obligate long-distance migrants which overwinter in sub-Saharan Africa and migrate to Palaearctic breeding sites.

We measured body condition and aerobic performances of birds at Ventotene islands - the first stopover site after crossing the Mediterranean Sea.

The data set comprises the following parameters:
