Parakeets can breed year round if conditions are right in their environment. Normal breeding season begins early in the year and continues until fall. It is very rare to see parakeets mating, but a male and a female must mate to keep the eggs fertile.
DISTRIBUTION: The Green Parakeet ranges from central Veracruz to northern Tamaulipas and eastern Nuevo Leon (Mexico; Howell and Webb 1995). It nests in Texas from the Gulf of Mexico on the Rio Grande delta (latilong 25097) to Mission (26098-B3) and ranges as far north as Kendall County (29098; Eubanks 1989, HHB).
