This video from Florida in the USA says about itself:
2 January 2017
A pair of Loggerhead Shrikes sing various short “songs” and food is presented by the male as part of courtship. One of the earliest songbirds in Florida to nest. They are not the most impressive singers of the bird world – calling with several short trills and buzzes – in this clip you will hear I believe 3 song or call variations. It was a very windy day – so windy it was hard to hold the camera still and get good sound quality – but that did not deter the birds!
