A $8 red shed trap laid over that part of the boat, or whatever.
Was down at a factory couple days ago, they had a movement operated distress sound... more bloody annoying than the birds.
And the guys recon the birds get used to it.
There are stickers of birds of prey that can be put on windows that are prone to bird strike (wood pigeons, tui, blackbirds etc)
Ultra sonic gadgets, know a few ppl who have had them for mice stuff like that. mess up some of their dogs , thats it.
Then there is the air rifle...good on pigeons, trouble is as soon as the flock in the tree reduces another pair move in to nest/ roost.
Now pigeons, there is a legit complaint.. sound like cats in high heels on the roof, mess up the roof and decks by perching on gutters.
What is the easiest way to chop down and kill a large mature phenex palm?
If extend the chop down logic as a soln... demolish the shed
