Flying objects

Last Wednesday, as we were looking at the Portimao skydivers and Alvor flamingos, Antje wondered what the collective word for a group of flamingos was. I remembered "a murmuration of starlings" but couldn´t help with the flamingos. Later on, I looked at a list of collectives and found some traditional ones "such as "a murder of crows" as well as some modern whimsies, such as " an absence of waiters" and "an actually of pedants" (which I am sure will appeal to Paulo a Pe); but nothing on flamingos. Then, on another site, which had "a trip of mushrooms" (which will appeal to Antje), finally I found it - "a stand of flamingos."
