Bird Census News 34/2

In this issue, you can read about the distribution of a relatively isolated breeding population of Goosander in the Alpine region. Thanks to atlas projects and special surveys, a marked range expansion in Switzerland is well documented. Although a 21% population size increase was noted between 1998 and 2013–2016, there are apparent regional differences. A significant decline appeared in the western bastion, most probably caused by the decrease of some fish populations, removal of nesting trees and predation by Yellow-legged Gulls.

The BCN also introduces two EBCC board members. You are welcome to read the interview with Henning Heldbjerg, the Delegates Officer and Bird Census News editing team member, and Danae Portolou, the Communications Officer.

Finally, a new part of the series introducing various monitoring schemes online tools presents the Danish Common Bird Census websites.
