This page is for the United Kingdom. corvids should not automatically be called a sanitary problem just because people dislike them. A real health risk must be assessed from facts, not from fear of wild birds.
A better way to think about risk
- Any wild animal can carry organisms, but normal distance, hand washing and sensible cleaning make the risk very low in ordinary situations.
- Food, rubbish and open waste attract many animals. Fix the cause first instead of blaming the birds.
- Droppings on benches, balconies or pavements can be cleaned in the same practical way as other outdoor dirt: wet it first, avoid dust, use gloves, and wash hands afterwards.
- During the breeding season, noise and defensive behaviour are usually temporary. Killing birds rarely solves the reason they came there in the first place.
If authorities are involved
Ask for a written explanation of the actual health risk, which law or local rule is being used, and which non-lethal measures have been tried. If this page is missing a good source for the United Kingdom, please contact me so I can add it.
