hi. i live in the countryside in ireland. at night, during the summer, only after dark, there is a bird that i want to identify. it makes a bleating sound like a sheep or goat. I know its a bird as ive heard it call as it flew overhead, but i have no glimpse of what it looks like. someone suggested a nightjar, but thats a very high pitched sound and not like what ive heard at all. around here, they are called "Sky goats" but i feel thats just a regional name, and may mean nothing elsewhere. any help would be great. thanks all
