| | EGGSHELL REMOVAL AND NEST IN RING DOVES |
 | | Doves brooding newly hatched squabs are more likely to arise, look down, and resettle than incubating doves, behavior that may increase the probability of detection and removal of an eggshell. |
 | | All doves were reproductively inexperienced when paired in breeding cages (81 X 46 X 36 cm), which were equipped with a food container, grit container, water dispenser, glass nest bowl (10.8 cm diam., 3.8 cm depth), and straw. |
 | | The reactions of the doves to the shells were either observed directly through one-way observation windows, or the location of the shell in the breeding cage was checked at 15 minute intervals for a period of one hour. |
