The abundance of nectarivorous birds in MT patches
was striking and may be related to the abundance of
wild bananas surrounding most patches. These appear
to be one of the main sources of nectar for the birds,
and are not as abundant in OK. Nectarivores such as
hummingbirds generally prove to be less vulnerable to
fragmentation than insectivores and frugivores (Bierregaard and Stouffer, 1997).
