Martins or swallows?

Been in bed with a nasty cough and chest infection since I got home from holiday Tuesday. Don't think the 5 hours on deck on the Atlantic helped matters being soaked, thrown around and sea sick.
These wee chaps visited me during the rain last night. They were dancing along the wire to get under the eaves.
I have an engagement tomorrow which I have to attend. Think I will be straight back to bed afterwards
