Screaming Parties are groups of two or more birds flying and calling loudly at low level - at or just above rooftop height - which means they are most likely breeding nearby.
Screaming Parties seen and heard in May are likely to be experienced breeders, but in June and July are probably younger birds pairing up for the first time.
Please don't report sightings of birds higher in the sky or feeding over water as they may be from some distance away.
