Introduction to Shorebird Mapping Project

Varied sources warn the birding world about the serious decline of the shorebird populations. Whether we are talking about Europe, North America, Australasia, the Oriental region, the Arctic or South America, shorebirds are declining with very few exceptions. There is little effort regards the monitoring of breeding shorebirds on a global scale, but WorldWaders are now trying to improve this situation in long term.


Objectives of the Shorebird Mapping Project

  • Monitoring the range changes of breeding populations of shorebirds worldwide.
  • Monitoring trends of shorebird populations.
  • Updating our knowledge on key habitat types used for each shorebird population.
  • Identifying key areas for breeding as well as migrating species.
  • Preparing conservation projects and supporting habitat management and governmental bodies decision making.
  • Identifying key threats and risks for different populations to support the development of pragmatic action plans.
  • Making monitoring as a key tool for conservation in areas where it is not or poorly used.
  • Popularise shorebird monitoring by providing easy to use online tools.

Project duration


Shorebird Mapping Project is a perpetual project with no specified end. Project kick off year is 2010.

Requested data

Breeding Shorebird Mapping Project
Many birdwatchers thinks a single nest data submission is non-sense as considered 'one drop in the sea'. Great picture of shorebird distribution could be drawn by those tiny dots on the map. Every nest counts if breeding is solitary. If a shorebird species is a colonial breeder or more pairs are breeding in the given area, a summed figure should be given and one placemark have to be added to the map. No need to mark every single nest.


It is always a question if failed nesting attempts should be submitted. The 'Breeding Shorebird Mapping Project" is not about the monitoring of breeding success but about the monitoring the number of birds starting to breed.


Non-breeding Shorebird Mapping Project

Typically coastal sites hold more birds than continental wetlands during migration with a few examples. WorldWaders database doesn't recognise a difference between data at the point of submission. It goes for an as large coverage as possible. This means counting result of every kind of habitat or type of observation is welcome. Counts needed to be carried out on a well defined site. Data of a specific site should not be merged with data of adjacent sites. Each sites should be individually monitored as data analysis is possible when sites are separated.

Data collection and usage

Shorebird breeding records collected via are analysed and the data used to support the objectives mentioned above. Data will be summarised on a regular basis and published online on this site. Conclusions of data analyses will be shared widely as a tool to support shorebird conservation activities. The Scientific Board of WorldWaders ensures proper understanding and usage of data and creation of well defined recommendation.


Every single record counts. We are encouraging anyone living close to a shorebird habitat, monitoring and recording shorebirds around local paths, to participate in this initiative and share records through WorldWaders. By pooling these shorebird records and sytematically analyzing the data, the conclusions and trends will be essential in improving conservation policies and management practices. Please join us today and add your data by following just a few easy steps.


Data security and privacy


Raw data submitted to WorldWaders is accessible to the administrators, the Scientific Board and the owner only. Raw data will never be sold! Raw data will be used for conservation purposes. Copyright of raw data will always remain at the owner of the raw data. Owner of the raw data is not equal to the submitter of data. All data kept on servers are save and archived frequently. Any data could be deleted by the owner or by admin. Not owned data visibility on the map is restricted to a certain level for a general user avoiding direct visit to any nesting sites.
