AnAge entry for Rissa tridactyla

Classification (HAGRID: 01281)
Taxonomy	Kingdom: Animalia Phylum: Chordata Class: Aves (Taxon entry) Order: Ciconiiformes Family: Laridae Genus: Rissa
Species	Rissa tridactyla
Common name	Black-legged kittiwake
Lifespan, ageing, and relevant traits
Maximum longevity	28.5 years (wild)
Source	ref. 450
Sample size	medium
Data quality	acceptable
Observations	In the wild, these animals have been observed to become better breeders with time but they also show a decrease in reproductive performance in their last year before they die. The latter could be caused by disease rather than ageing since it was observed in breeders of all ages [0057].
Life history traits (averages)
Female sexual maturity	1,460 days
Male sexual maturity	1,460 days
Incubation	27 days
Clutch size	2 (oviparous)
Clutches per year	1
Weight at hatching	36 g
Adult weight	317 g
Postnatal growth rate	0.184 days^-1 (from logistic function)
Metabolism
No information on metabolism available.
