The melodious blackbird (Dives dives) is a species of bird in the family Icteridae, the oropendolas, New World orioles, and New World blackbirds. It is found from Mexico to Costa Rica. The melodious blackbird was formally described in 1830 with the binomial Icterus dives. It now shares the genus Dives with the scrub blackbird (D. warczewiczi). The two form a superspecies and some early twentieth century authors treated them as conspecific.
The melodious blackbird is monotypic. Male melodious blackbirds average 25.5 cm (10 in) long and weigh 98.3 to 102 g (3.5 to 3.6 oz).

Likely
About 40% of wildlife watchers report a Melodious Blackbird sighting in Calakmul Biosphere Reserve on a given day, based on 344 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 14th most-seen of the 271 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
January to April
In those months about 50% of wildlife watchers report a Melodious Blackbird in Calakmul Biosphere Reserve on a given day, against about 30% in May–June and October, the lowest months. Those are among Calakmul Biosphere Reserve's driest months, with about 25 mm of rain a month against 130 mm in June.

GBIF citizen-science records
It is estimated from how often the Melodious Blackbird is recorded against all the birds logged in Calakmul Biosphere Reserve (344 verified sightings from 2019 to 2026), 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.
