Pheasants and ticks: our letter in The Courier

Pheasant -in -Woodland -wwwdavidmasonimagescom

The following letter was published in The Courier on Saturday 7 April:

Sir, - pheasants are competent vectors of some (not all) Borrelia sp - (the group of bacteria that causes the various types of Lyme disease). This means that ticks can pick up some strains of the bacteria from pheasants and pass it to other animals including people.

However, there are many other animals that are vectors of Borrelia species via ticks. Recent research on the continent confirms that small mammals, such as wood mice, are probably the most important. Others include grey squirrels, stoats, weasels, probably other small to medium sized mammals and many bird species. Deer host ticks, but aren’t good vectors of Borrelia.

It is likely that high densities of pheasants (and deer) in an area will alter the mix of Borrelia strains there by mopping some up and transmitting others. Whether pheasants have significant implications for human health is currently unclear.

One thing that is clear, though, is that pheasants are not fundamental to the tick life cycle and Borrelia transmission as suggested by George Murdoch (Disease? It’s all about shooting, April 4th).

The idea that reducing pheasants will wipe out the disease ignores the role of the other animal hosts and is not supported by research, as suggested.

How you can support our ongoing pheasant research

We're working hard to answer the following questions:

  • How do we release birds that survive better?
  • How can we improve return rates?
  • How can we improve the release environment for pheasants and other wildlife?

We are the only organisation searching for the answers to these questions but we can't do it without your help.

Please give what you can afford to help our dedicated team of scientists. Your support for this research can help increase the positive impact of game management for years to come.

How your support helps

£50 – to collect five soil samples from a release pen and look for gapeworm eggs and larvae in the laboratory

£175 – to conduct a day’s butterfly count and floral surveys in woodlands where pheasants are released

£480 – to radio tag and track a hen pheasant twice a week throughout the breeding season

Ticks and pheasants

Congratulations on your measured response to The Courier about pheasants and ticks. It is increasingly difficult to counteract the loud anti-field sports animal cruelty lobby. Excellent sensible incontrovertible responses like yours are very important and a vital cog in combatting the "anti" lobby who are happy to play fast and loose with their facts and the truth in their statements.

Ticks & Lyme Disease hosts

Great to see deer not being scapegoated for the spread of Lymes Disease, I'm sure that must greatly disappoint Natural England with their deep rooted prejudice against them. A couple of species not mentioned as competent reservoir hosts for Lymes Disease are both the Red Squirrel and Hazel Dormouse see :-https://www.sciencedirect.com/science/article/pii/S1877959X13000800 http://europepmc.org/articles/PMC4054143
