This blackbird visits the feeding station on our window pretty much everyday. He's fond of meal worms, that's what we mainly feed him. There's no actual menu. I say "this" blackbird but I suppose there may be many and I'm simply seeing them one at a time and never the actual whole group. This assumes a certain expertise and strategy amongst blackbirds whereby they like to fool and confuse humans by only ever appearing one at a time in a number of feeding locations.
Naturally I've been well and truly fooled by this clever ploy even though it may not be a real thing at all. I'm also not sure what the purpose of it might be. More likely it's just that blackbirds like to move and operate on their own and appreciate and value the joy of their own free time without suffering annoying interruptions from other passing blackbirds airing their own disagreeable opinions as they eat. Perhaps we can all learn something from observing those solitary blackbirds.
After the blackbird's third helping of meal worms he silently winked and watched me leave, en-route for the local showgrounds where an empty pavilion has been converted into a Covid vaccination centre. I parked up, wandered through the slush and into the building, then into to a pristine booth where I duly received a dose of Pfizer's best medicine from a young military nurse dressed in combats. Then a fifteen minute wait to ensure all is well and finally joining in on an OAP shuffle parade, straight back to our vehicles and home. So far I've no side effects to report other than my own already well established ongoing internal conflicts. Phew ... safe at last ... almost.
