Bird damage
Soft fruit stripped as it ripens, and fruit buds removed from currants and gooseberries over winter. On cherries and blueberries in particular, an unprotected crop in a British garden is a bird crop, and the honest answer is netting or nothing.
Caused by: Chiefly blackbirds, starlings, pigeons and bullfinches
Nothing available to a home grower will fix this
There is no deterrent that works for a whole season. Scarers, foil strips, glittering tape and models of predators all work briefly and then stop as the birds habituate. Physical exclusion is the only measure that holds.

Stated plainly because the alternative — listing deterrents that stop working within days — costs growers a crop while they wait for them to take effect.

Described view
A cherry spur in late winter stripped by bullfinches: the fat flower buds removed cleanly at the base leaving pale torn scars on the wood, with the narrower pointed leaf buds beside them untouched, and shed bud scales visible on the branch below
What brings it on
Fruit taken as it colours, often the day before the grower intended to pick. Bullfinches additionally strip dormant fruit buds from currants and gooseberries in late winter, which costs the following season's crop before it exists.

Preventing it
Ordered by how much difference each measure actually makes, not by how often it is repeated.
- Net the crop, using netting with a mesh small enough that birds cannot get a head through, held taut on a frame clear of the foliage. A fruit cage is the permanent version of the same idea.

- Choose a rootstock or a form you can actually net. This is the practical argument for a dwarfing cherry and against a standard: a five-metre tree cannot be protected, so its crop belongs to the birds whatever else is done.

Dealing with it once it is there
- Pick as soon as fruit is ready rather than waiting for perfect ripeness, where netting is not practical.

Widely repeated, and not supported
Recorded so GrowingHQ can address them. These are not alternative approaches — they are things the evidence does not back.
“Hanging up old CDs, foil strips or a plastic hawk will keep birds off fruit.”
Visual and audible scarers work for a few days and then fail as birds habituate to them. They are not a substitute for netting on a crop worth protecting.

What it affects
On sprays and treatments
GrowingHQ does not tell anyone what to apply, at what rate, or how often. Pesticide approvals differ by country, change without notice, and the product label is legally binding — it is also the document you are holding. What is described here is cultural and physical control, which is what a home grower can act on without a label in front of them.

Where this is one of several causes that look alike on a particular plant, GrowingHQ publishes the differential rather than the general answer.
