The DSG maintains a register of past and ongoing projects. European seaduck projects are available here and a searchable version for this website is currently under development. If you are a member and have project information you would like to contribute, please contact the Secretariat for further details.

Monitoring the sex ratio of ducks in the Western Palearctic

Sex ratios of most ducks can be recorded during mid winter counts and help us understand changes in the structure of their populations. The DSG maintains a system for recording these data, in conjunction with those national waterbird monitoring schemes that also collate sex ratio data. Further details, including a data submission form, are available here.

Developing European duck wings surveys

The DSG and national partners are working to strengthen national duck wings schemes and re-establish European-wide coordination in order to understand more about duck population demography and the composition of hunting bags. Further details can be found here.

Aasla database

Dr. Lennart Saari has censused birds for four decades strictly using the same methodology at Aasla (60º 18´ N; 21º 57´ E), in the Archipelago Sea of southern Finland. His database is now available for downloading and the only requirement for use of the dataset is to inform Dr. Lennart Saari how you intend to use his data by contacting him at lennart.saari (at) and co-authorship for him in any resulting publications.

Braz Merg ringed RHearnColour-marking register

The maintenance of a register of colour-marking projects is essential to ensure mark types are not duplicated. DSG maintain a register of projects, and information on many existing projects in Europe can be found on the Colour-ring birding website. If you would like to register a new project please contact the Secretariat. For projects in Europe using nasal saddles, please contact David Rodrigues.

Information on colour-marking in Asia is hosted by the East Asian-Australasian Flyway Partnership.

RIMG1035Ageing & Sexing Guide

The DSG is developing a series of ageing and sexing guides to provide species specific guidelines for fieldworkers. The guides produced to date can be found here. If you are in a position to enhance existing guides, or produce them for species not yet covered by the series, please contact the Secretariat for further details.

0289_Black-bellied_Whistling-Duck_03-23-2012_3Waterbird Population Estimates

DSG members support the assessment of population size and trend for all duck populations through the provision of data and expertise. Current estimates can be found on the WPE website.

Revised estimates for migratory African and European populations have recently been finalised for the AEWA Conservation Status Report 6 and WPE6 (covering all other duck populations) is currently being prepared. Further details about this process can be found here.

RBM flywayFlyway mapping

Accurate flyway boundaries for all duck populations underpin the use of population estimates by agreements and conventions such as AEWA and Ramsar. Boundary maps for African-Eurasian populations can be found on the Critical Sites Network Tool (and a review of this work can be found here), but those for other duck populations do not yet exist. These are being drafted as part of WPE6 and flyway maps for South American ducks will be available for comment in due course. Further details about this process can be found here.

PH Duck logo.1Philippine Duck conservation

A collaborative project between Manchester Metropolitan University, the University of Chester and the University of the Philippines to assess the distribution, abundance, status and habitat use of the Philippine Duck and to assess hunting pressure and egg collection rates. Further details are available on the project blog.
