The Cuban crow (Corvus nasicus) is a crow species native to the northern Caribbean. Two other Caribbean crow species, the white-necked crow (C. leucognaphalus) of Hispaniola and the Jamaican crow (C. jamaicensis), appear to be very closely related to it, sharing several key morphological features. The ancestor of the fourth and fifth species from this region, the Hispaniolan (C. palmarum) and Cuban palm crows (C. minutus), would appear to be a later arrival (at least in evolutionary terms); both species show more similarities to the fish crow (C. ossifragus) of mainland North America and two Mexican species. This is despite C. minutus being sympatric with C. nasicus on Cuba, indicating two distinct arrivals of crows onto the island, and a resulting niche differentiation, similar to C. leucognaphalus and C. palmarum on Hispaniola.
A stocky, medium-sized (40–42 centimetres or 16–17 inches in length) forest crow, the bill of this species is long and deep with a gentle curve towards the tip giving a large headed profile. The nasal bristles sweep forward then upward and frequently reveal the nostrils which are hidden in almost all other members of the genus... Wikipedia →

Rare
Under 5% of wildlife watchers report a Cuban Crow sighting in Havana on a given day, based on 27 verified sightings from GBIF citizen-science data. It is the 139th most-seen of the 183 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Cuban Crow in Havana on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Cuban Crow sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Havana, in our data
Havana is the only city on Wallace's Line with enough records to rate Cuban Crow sightings: under 5% of wildlife watchers there report one on a given day.
Same order: Passeriformes
The closest relatives of the Cuban Crow that you can see in Havana (order Passeriformes, Perching Birds) are House Sparrow (about 70%), Northern Mockingbird (about 70%) and Cuban Blackbird (about 70%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Cuban Crow is recorded against all the birds logged in Havana (27 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
