Because of shortage of fresh green growth, pigeons are causing a lot of damage to the developing blossoms of many different fruit trees, but in particular to plums and green gages. This will carry on until more attractive sources of food become available.
Without blossom, there can be no fruit set, and so no fruit! Therefore if damage is only slight, no action needs to be taken. If the cold period continues, pigeons are capable of literally stripping off all the blossom. Black cotton threads, woven through the flowering branches, will usually stop the damage. Just wind it around the tree (slip the spool onto a rod or dowel to make things simpler) so that the threads are about six inches apart. What happens is that the bird flies towards the tree, doesn’t see the thread, touches it with its wing, gets a fright, and flies off. No damage to the bird is done, and it helps save the blossom!

It is at this time of the year, when the first newly emerging little leaves are a great attraction in all areas where pigeons are present in great numbers, where field rape is grown. The pigeons show a great desire to vary their food source. After having grazed the rape fields, the pigeons will move for a while to the nearest hedge cover. From that point they will attack any type of plum or green gage, severely damaging any blossom or young green leaves.
The net result is that the crop prospects of those trees will be set back greatly and may result in no crop at all. Anything that can be done to scare the pigeons away is worth trying. A mixture of various deterrents is better than just one.
The length of the period during which the trees are at risk will greatly depend on temperatures and type of weather. A long cold spell is the most damaging period. This season is likely to be a bad season as warm spring weather seems not to be expected just yet, according to the 10-day forecast by the weather experts.

Even though the trees will be looking bare, it’s important to apply cotton threads to pear and plum trees as soon as the leaves have fallen. This is a good method of deterring pigeons and bullfinches who otherwise will eat the fruit buds, essential for next year’s crop, in pears and plums. Ordinary cotton is fine, just wind it around the tree (slip the spool onto a rod or dowel to make things simpler) so that the threads are about six inches apart. What happens is that the bird flies towards the tree, doesn’t see the thread, touches it with its wing, gets a fright, and flies off. No damage to the bird is done, and it helps your tree!
