I would be distressed to witness TDs (or other species such as orioles or hoopes) being blasted out of the sky in Malta or Cyprus.
But, given that it is a longstanding activity, what percentage of the UK decline can be attributed to shooting in Mediterranean countries? Could it be less than five per cent?
How much are farming or other factors - either here or in their winter territories - to blame? Can they be quantified?

Does anyone know what is the current status of TDs in France and the Benelux countries? Does the species summer in Scandinavia?
Evidence for a population crash across the species' range:

On the subject of shooting, there is an element of hypocrisy. Plenty of people in Lincolnshire and elsewhere enjoy shooting wood pigeons. They can justify it by claiming WPs are a farmland pest.
But what if the position was reversed - with TDs being common and WPs were rare? How would the
debate change?
Woodpigeons possibly part of the problem through disease transmission:

http://www.ncbi.nlm.nih.gov/pubmed/25212735Woodpigeon + Corvid numbers likely out of equilibrium given the lack of Goshawks* in eastern England.... disease + nest predation
So perfect storm of habitat loss on breeding + wintering areas, continued hunter off-take + disease
*don't go there
