For birders all over the world

Trip list

Note: (i) Total numbers of individuals observed over the course of the trip is provided; for the commoner species, these are mostly rough estimates.

(ii) The second number represents the number of instances with which a species was encountered; one instance is equivalent to one individual or more at a given location on a given day. If we encountered the species again later that day at another location, or at another location on a later day, or at the same location on a different day, these all register as another instance. Not very quantitative, but it provides some indication of how common a species was (i.e., the bigger the number of instances, the more common it was).
