Patterns of food preferences in mourning doves

Article Abstract:

A comparison is presented on food preferences between captive and free-flying mourning doves for both cultivated and wild food sources. Preferences were negatively associated with cellulose-lignin levels and positively associated with nitrogen-free extract levels in food sources. Both captive and free-flying doves foraged selectively, but preferences were not clearly detectable in free-flying populations.

Dietary overlap and foraging competition between mourning doves and Eurasian collared-doves

Article Abstract:

Diet selection and degree of dietary overlap is measured and compared in 2 dove species in a captive cafeteria experiment. The aggression and competitive ability are measured in these species in 3 captive competition experiments. The effects of the body size, temperature, and food distribution on aggression and competitive ability of both species are evaluated and intraspecific aggression levels and competitive ability within each species is measured.

Molt of after-hatching-year mourning doves

Article Abstract:

Research using captive and wild mourning doves has been able to establish the number and timing of annual molts and the link between reproductive activity and molt during the annual cycle. For both captive and wild doves, mean overall body molt scores rose in Aug, peaked in Oct, fell through Dec and stayed low from Jan to Jul. Similar trends were seen for mean molt scores for body regions, although the back and rump were generally the first regions to initiate molt. It seems that captive and wild doves have similar molt cycles, with the molt cycle giving sufficient time for the molt to be completed before the onset of winter.
