Pigeons are among the most broadly distributed and widely recognised bird groups. All pigeons belong to the family Columbidae, which has 42 genera and 316 species. Although the number of species of pigeon that can be found around Paluma is not particularly large (about 8 rainforest species in and around the village) we host some of the most striking and colourful species to be found in Australia. The white-headed pigeon (Columba leucomela) belongs to the former group, having a striking black and white plumage with just a dash of colour around the eyes and bill.
In Paluma it can be seen flying overhead in small groups, and foraging in the canopy of Bollygum (Neolitsea) and other local fruiting trees. It is found from Cooktown to Eden in NSW predominantly in rainforests and gallery forests along creeks and gullies. While not uncommon, it tends to feed quietly in the mid to upper canopy so it is not easily spotted along the village tracks.
Although it is not threatened if was previously a preferred target for hunters, which depressed populations along much of its range.
The White-headed Pigeon is the only native member of genus Columba in Australia. The only other member in Australia is the ubiquitous and frequently maligned Rock Dove or Feral Pigeon (Columba livia) which occurs worldwide in areas of human habitation.
Pigeons are monogamous with both parents helping to raise their young. There are almost exclusively seed eaters (granivores) or fruit eaters (frugivores). When feeding their young, many other vegetarian bird species switch to energy and protein rich insects to promote rapid nestling growth. Pigeons, however, feed their young on a highly nutritious “crop milk”, which is a secretion from the lining of the crop (a muscular pouch near the throat of many birds). This useful trait is analogous to lactation in mammals.
Crop milk (often called Pigeon milk) is produced only by pigeons, although flamingoes and penguins also feed their young from secretions from different parts of the gut.
The extinct Dodo and Solitaire (Genus Raphus) are also formally included in the pigeon family (Columbidae).
Australia Post published a series of 4 pigeon stamps in 2021. Three of these are to be found in Paluma, including the White-headed pigeon.
