Similar in markings and colours, only a trained eye can easily determine the gender of adult pigeons. The male pigeon tends to have a thicker head and wider neck, looking more robust than a female of the same species. The natural habitat of a pigeon is coastal cliff tops. But, with humans offering a ready food supply in the shape of waste, the ledges of buildings, including homes and city centres properties, make the perfect substitute for the cliff edges they would normally occupy. This is a respiratory disease that can be fatal. It is caused by inhaling the fungus that grows on bird droppings. Hence, many people living in flats with balconies will need to take measures to keep pigeons from roosting on balconies etc. Pigeons also carry Candidiasis, a yeast or fungal infection that can be unpleasant. In captivity a pigeon can live for up to 15 years however in the wild, a pigeon tends to live for between years. Evidence suggests that pigeons mate for life and although monogamy is mainly followed, extra-mates are not uncommon, something that is triggered by the male. Female pigeons produce crop milk — also known as pigeon milk — which she reproduces to feed her young. This means that pigeons can breed all year round.
