Turtle Doves are in steep decline – their population fell by 95% between 1967 and 2012. One reason for this is the lack of seed food on farmland in the summer.
The turtle dove is a summer visitor arriving in late April and leaving in September. Without the right habitat and food source, it can’t maximise its’ possible 3 broods a year. They are on the ‘Red List’ of conservation concern. https://www.bto.org/our-science/publications/psob
Such populations as exist are mostly found in East Anglia so we’re really lucky to have not one but two pairs of turtle doves at opposite ends of the site. One can hear their gentle purring call in the mornings and evenings. The RSPB is kindly providing exactly the right food/seed for them by way of encouragement.
