Most of the population is resident, but some northern birds Migrate south to Mexico in winter. The Mexican Duck was formerly considered a good species, but hybridisation with the closely related Mallard , which has spread into its range, has introduced genes from that species into ''diazi'', and the taxonomic status is consequently compromised. It is a bird of most Wetlands , including Pond s and rivers, and usually feeds by dabbling for plant food or grazing. It nests usually on a river bank, but not always particularly near water. Both sexes of this 51-56 cm length Bird resemble a female Mallard , but with a slightly darker body. Mexican Duck is mainly brown, a blue Speculum edged with white, obvious in flight or at rest. The male has a brighter yellow bill than the female. The male has a nasal call, whereas the female has the very familiar "quack" always associated with ducks. The binomial name commemorates the Mexican engineer and geographer Augustin Diaz . Reference ''Wildfowl'' by Madge and Burn, ISBN 0-7470-2201-1 |
