... for increased levels of free radical production resulting from flight effort. Unexpectedly,the change in serum antioxidants was modulated by age, with older pigeons depleting more serum antioxidants, perhaps mirroring to some extent the use of antioxidants for maintaining the redox homeostasis. This was evident...

..., but this pattern varied across the nests. Our results show that (i) in general, younger nestlings actually have to cope with a high free radical production, and (ii)the ability of wild nestling kestrels to cope with oxidative stress is not affected by carotenoid availability. * Author for correspondence (e...

... that might protect carotenoids from free radical attacks and make them available for sexual advertisements. We tested this hypothesis in the zebra finch, a passerine species with a carotenoid-based signal: the colour of the bill. We simultaneously manipulated the availability of carotenoids and of a non...
