Community diversity
Tallies based on entries in Howell and Webb (1995) and Howell (1999).
- Total number of bird species recorded (including Gaumer records): 240
- Total number of bird species recorded (excluding Gaumer records): 208
In the early 1800s, George F. Gaumer was an ornithological collector based in the Yucatán. His collection, much of which new resides at the University of Kansas Museum of Natural History, includes 32 species reported from Cozumel. However, Gaumer is known to have made many errors in labeling this specimens, so many of his localities are now considered to be incorrect. See Parkes (1970).

Notes: An additional endemic subspecies, the Cozumel Green Jay (Cyanocorax yncas cozumelae) was described by van Rossem (1934), but the description was based solely on two dubious Gaumer specimens. There are no subsequent records of Green Jays on Cozumel.
The subspecies of the Dusky-capped Flycatcher native to the Yucatán and Cozumel, Myiarchus tuberculifer platyrhynchus , was first described from a Cozumel specimen (Ridgway 1885). However, the subspecies is not endemic to Cozumel (contra Howell and Webb 1995).
