I've noticed that it is often "ostriches" or "ostrich" according to different sources. Does it vary by the dialect of English?
Normally I'd use Google to determine something like this, but unfortunately the search for "ostrich" plural is overcounted because of references to the singular "ostrich".
Dictionaries laying around were
inconclusive. One listed plural as
"ostrich" another listed "ostriches". In
cases where the dictionaries disagree or
where there are multiple possible
solutions I tend to go with the more common answer. That is something
that can be easily found by googling,
but not in this case

Where the plural occurs in the citations in the OED, it is ostriches. However, those who make ostrich the plural can appeal to the precedent of the hunter’s plural in lion, tiger, elephant and so on.
