2021 is Year of the Swift for Navan as declared by Wild About Navan. This 27 March 2021 article in Meath Chronicle gives more information
In April 2017, Peter McCarron placed swift nest boxes on the chimney of his house and is playing the calls from a speaker located near to the boxes.
Peter’s house is located just across from the Nanny River Estuary on the border of Counties Louth and Meath. In the summer time there are lots of midges and mosquitoes just above the water so perhaps they will also tempt the Swifts. He often sees Swifts flying over his house so fingers crossed they will find the nest boxes.
