Reseña del libro "Mourning Dove Breeding Population Status, 2001 (en Inglés)"

This report includes Mourning Dove Call-count Survey information gathered over the last 36 years within the conterminous United States. Trends were calculated for the most recent 2- and 10-year intervals and for the entire 36-year period. Between 2000 and 2001, the average number of doves heard per route decreased significantly in the Eastern and Central Management Units. No change was detected for the Western Unit. Over the most recent 10 and 36-year periods, significant declines were indicated for doves heard in the Central and Western Units. Additionally, in the Eastern Management Unit, a significant decline was detected over the most recent 10 years while there was no trend indicated over 36 years. In contrast, for doves seen over the 10-year period, a significant increase was found in the Eastern Unit while no trends were found in the Central and Western Unit. Over the 36-year period, no trend was found for doves seen in the Eastern and Central Units while a decline was indicated for the Western Unit.
