The Shropshire Ornithological Society said numbers of the birds have been in decline, and it wanted a record of rookeries in the area.

It has asked people taking part in the survey between now and the end of the month to complete an online form, external, with another count due to follow after that.

At this time of year, the organisation said rooks return to their noisy colonies and start nest-building and laying eggs and it was important to record this activity.
