The latest lesser prairie-chicken survey shows bird population trends remain stable after six years of aerial survey data collection. The survey indicates an estimated breeding population of 33,269 birds this year, up from 24,648 birds counted last year. Though scientists are encouraged by the numbers, they know that year-to-year fluctuations are the norm with upland birds like the lesser prairie-chicken.
“The survey results indicate a 34% increase in the number of birds, but we don’t read too much into short-term population fluctuations,” explained Roger Wolfe, WAFWA’s Lesser Prairie-chicken Program Manager. “The monitoring technique used for this survey is designed to track trends which more accurately reflect the amount of available habitat and population stability. The bottom line is that the population trend over the last five years indicates a stable population, which is good news for all involved in lesser prairie-chicken conservation efforts.”
Lesser-prairie chickens can be found in four ecoregions in five states: Colorado, Kansas, New Mexico, Oklahoma and Texas. Wildlife biologists note prairie chicken numbers regularly fluctuate up and down from year to year due to changes in habitat conditions mainly influenced by weather patterns. The surveys this year indicated apparent population increases in three of the four ecoregions and range-wide, with an apparent decrease estimated in the fourth ecoregion.
