Many readers ask for information about such things as incubation periods, age at fledging, and age of sexual activity. This page provides those numbers based on data collected by Dr. Charlotte Van Hoozier for all eggs produced by her pair of silver whitetail diamonds during the year 2000.
Dr. Van Hoozier purchased two white tail diamond doves on September 18, 1999. Both doves were reported to have an age of 9 months verification of this age was impossible. Neither of the two birds were banded. These two birds began
their mating activity on January 15. 2000 and laid their first clutch of eggs between January 20th and January 22nd. The following table displays summaries of the data collected during the year.
Total number of clutches: 15
Total number if eggs laid: 30
Total number of eggs hatched in 2000: 15
Total number of eggs hatched in 2001: 2
Total number of eggs that did not hatch: 13
Total number of birds alive at fledging: 17
Total number of birds that died before fledging: 1
(This bird probably died because it was much smaller than the first baby that was hatched and did not obtain
sufficient food from the parents. Future small babies were provided with supplemental feeding).
