Protect Grapes from Birds

[Jana-Agtek. Agrow]

Hello! The other day I sorted out how to protect grapes from birds. https://www.agrowgroup.com/non-invasive-methods-for-protecting-grapes-from-bird-predation.html
And some papers mention the use of ultrasonic sensors to repel birds.
Have you used this approach and how did it work?

Didn't work for me. Likewise, the toy owls and other plastic look alikes.

I don't bother with them anymore as we have an abundance of grapes, more than we can use. The birds take what they want, and we still have plenty.

My air dancer working protecting the cherry tree. The cherries will be ripe in a week. The efficiency of the device ill be evaluated then.

Three robins were chased from the cherry tree. Th air dancer was elevated by using a step ladder and moved closer to the cherry tree. Later on in the day no birds were observed.

Thank you for sharing. The birds must love your vineyard.

I live in England, so I shut the greenhouse door.

Three robins were chased from the cherry tree.

Caught me for a second, then I remembered Americans call a variety of thrush 'Robin'. The original robin redbreast of Olde England is a solitary insectivore, so it really didn't fit.

I tried all the internet panaceas, non worked except the air dancer. Movement seems to be the working function and close to the object desired to protect. Birds in large numbers can destroy a single cherry tree in a few nights also vrey hard on blueberries and srawberries. Squirrels damage a lot of fruit also. The moving air dancer is the best defence to date.

The NA Robin has the same colouring as the UK version, but is twice the the size. Ours usually feeds on earth worms and I notice usually avoil plant grains.
