We have had the good fortune to have been able to see, band and photograph more albino bluebirds this year. The first on July 7th and now the second and third on July 14th. We would like to thank Steve Disher for allowing us to take the photos below of the pair of albinos at his residence. Steve also had one albino from the same pair in an earlier nesting. This pair is 15 miles from the previous pictures of the single albino ( at the Floyd Bontrager residence). We asked (via the internet) about the possibility of this number of albinos this close together and below is one response from the Indiana Dept of Natural Resources Non-game Biologist, John Castrale! |

Albinism is rare, but has been documented in over 300 species of North American birds. It may occur at a frequency of about 0.5%. There are several degrees of albinism (total white feathers and pink eyes to just a few white feathers); birds with lack of pigment in the eyes may have weak eyesight. White feathers tend to be brittle and may break off easier. The causes are genetic (which is why there may be clusters of cases in an area), but patches of white feathers may be caused by tissue injury. |
