"Mr and Mrs"

Is it doves that mate for life? ... or is it swans ...

Hello Sheila, I've heard of a swan and albatross via David Attenborough so I paste the results from a Google search:
Many birds form long-term pair bonds that may last a lifetime, or only several years. No species is known to always mate for life; studies show that most monogamous species are more like humans, in that some pairings last only a short time, some for years, and a few for a lifetime.

Birds known to form long-term pair bonds that may last a lifetime include swans, geese, most hawks, eagles and falcons, most parrots, albatrosses, ravens, pigeons and doves, and more. Birds as a class contain more monogamous species than not, though some species switch mates more often than others. Most migratory songbirds find a new mate every year. Relatively few bird species are polygamous (males mate with many females), and just a few are polyandrous (females mate with many males).

Also like humans, though, even pair-bonded birds are known through genetic testing to occasionally "cheat" on their partners!

Interesting that Tommy ... thanks

Welcome Sheilar.

I have a Mr & Mrs, too, plus a youngster who is still following them around a lot. I get worried when I only see one of the pair because they are usually inseparable. They are beautiful birds, so elegant.
