Topsy the Crested Pigeon
Over recent weeks my wife and I have been intrigued by one of our resident Crested Pigeons – shown in the photos on today’s post. We suspect that she is a female because another pigeon was displaying to her recently. We have given her the name “Topsy” because she has some extra-long feathers making up her crest. I am not sure what has caused this slight aberration, but it certainly makes her stand out from the other pigeons in our garden.
Like all of the Crested Pigeons and Spotted Turtledoves resident in our garden and on our five-acre block, “Topsy” comes frequently to our bird baths for a drink. Today, while I was having a cuppa after lunch she came once again. She spent a few minutes on a nearby branch preening before flying down for a drink. She then flew down to the ground and sat down in the sunshine. She immediately lifted up one wing and held it with the underparts exposed to the warm sun. “Topsy” then stood up, changed position and raised the other wing in the same manner.
While I haven’t seen this sunbathing behaviour in many species I have observed it in Spotted Turtledoves, Red wattlebirds, Noisy Miners and Australian Magpies. It is surprising that there is very little mention of this behaviour in the literature, but this article on the Australian Birdlife site gives the topic a good coverage. The article suggests that this sunbathing behaviour could be aimed at ridding the birds of unwanted lice.
