Understanding and monitoring ireland’s hen harrier population
The Irish Hen Harrier Winter Survey (IHHWS) was established in the winter of 2004/5 to investigate the least studied, yet largest part of the Hen Harrier's annual cycle and to better understand and conserve the Hen Harrier in Ireland. Join our skilled and determined group of surveyors monitoring Hen Harrier during the non-breeding period.

1. select site
The IHHWS can allocate you a site to survey, or you can use your own initiative and select a potentially suitable location to check each winter, e.g. reed bed, marsh, bog etc.
2. watch
Survey dates are set for the 1st day of each month (from August to March) or as close as possible. Observers watch their sites from at least 40 minutes before sunset or sunrise.
