I have lived in Upper Norwood since 1997. Upper Norwood is one of the greenest parts of Greater London and I am fortunate that my home overlooks an historic park. The prevalence of greenery leads to a diversity of wildlife, including foxes and owls.
From time to time an owl’s mournful cry reaches my ears. I like to think that he (or she) is the same owl. However given that I have resided in the same spot for some 20 years this is impossible.
Below is my poem “Owl
“Owl” can be found in my collection of poetry “Refractions” https://www.amazon.com/dp/B01L5UC2H2

Not impossible, just unlikely. Owls can sometimes live 20 years or so. Usually captive ones rather than wild ones. However, while it’s more common for captive owls to reach advanced ages than wild ones, some wild owls have been known to do so too.
Having said that, I think it’s more likely that the owl you’re hearing is the grandchick of the one you heard when you first moved there, possibly even the great-grandchick.
Thanks Tori. That is very interesting. Either way its good to think that there may be a connection between the owl I first heard on moving to the area and the bird I hear now.
Best, Kevin
Yes, I’m sure it is. I know I’d like to think so in your position.
I think owls are amazing birds, Kevin. A lovely poem.
I agree with you that owls are amazing birds, Robbie. I am pleased you like my poem. Many thanks for your comment.
