I saw and heard a (very) noisy group of 10 CBCs in vegetation along Tarban
Creek (Riverglade Reserve), Hunters Hill (in Sydney) last Saturday. This is
the largest CBC group I've seen in this locality in the 8 years of regularly
visiting the reserve. However, in consulting HANZAB, foraging/roosting
groups of 30-60 individuals have been recorded elsewhere in the species'
range, and there is one record of >60 migrating birds.

What's the most CBCs you could expect to see in a flock? Do any other cuckoo
species fly in flocks like that?
