Intraspecific variation in length of incubation period of Avocets Recurvirostra avosetta.
Pied Avocet (Recurvirostra avosetta) Science Article 2 abstract This paper investigates factors influencing the intraspecific variability of incubation periods in Avocets Recurvirostra avosetta. The length of the incubation period of 278 clutches ranged from 19 to 34 days with an average of 23.1 days. Incubation period was influenced by clutch size. There was a seasonal […]

Estimation of total numbers of Pied Avocets Recurvirostra avosetta using a moulting site in the Danish Wadden Sea.
Pied Avocet (Recurvirostra avosetta) Science Article 3 abstract After the breeding season Pied Avocets Recurvirostra avosetta gather at moulting sites. Counts show that some of these sites host large parts of the total population, but it is not known how many individuals use a particular site over a season (volume of a site). Here we […]
