| The range of the slender-billed grackle, in Mexico | |
The slender-billed grackle (Quiscalus palustris) was a species of bird in the family Icteridae. The species was closely related to the western clade of the great-tailed grackle, from which it diverged around 1.2 million years ago.
The slender-billed grackle was endemic to central Mexico. It is recorded as having occurred in the Valley of Mexico and the Toluca Valley. Although later records indicated that it might be a marsh specialist, older observations recorded in the General History of the Things of New Spain by Fray Bernardino de Sahagún indicate that it was formerly found in cultivated areas and towns.
The slender billed Grackle was originally known from the Rio Lerma area in Mexico. They have not been recorded since 1910 due to their extinction. There are several records of the Slender-Billed Grackle from three different habitats such as wetlands, cultivated plots, and human settlements. Slender Billed Grackles inhabited marshes and borders of the lakes. Emergent aquatic vegetation was commonly used for nesting amongst the Slender Billed Grackles.
The Slender–billed Grackle usually nested in marshes and aquatic vegetation; however, as the population in Mexico increased they were able to adapt to the changes in the environment and learned to nest in towns and cultivated plots. The Slender-billed Grackle hatched their eggs in reeds.
The food of the Slender-billed Grackle consisted of animals, plants and fruits. It mainly ate worms, flies and maize. The Slender-billed Grackle also tended to be in groups called flocks.
When initial European settlers came to Central Mexico they observed that the Aztecs targeted the Slender Billed Grackle, however the reason for this is partially unclear. Some speculate that they were targeted because they were seen as pest who ate their crops while others believe it was to use their feathers for headdresses. They choose to use their black tail feathers rather than their bright green feathers for reasons still not known.
Also during Izcalli, the Aztecs' month in which they sacrificed a variety of animals to their gods, they chose to use this bird for sacrifice to their fire god. The reason for this is not yet known to historians however many believe since they were abundant and considered a nuisance.
