So much in love
This species did not arrive in Britain until 1953, and bred for the first time in 1956. Due to its long breeding season (March - October), it was quickly able to colonise the whole country.
They are said to mate for life and pairs become inseparable. The eggs are incubated by the female during the night and by the male during the day. Therefore don't get too worried if all of a sudden your pair of doves becomes one, as it may simply mean they have started nesting.
