Can birds survive trichomoniasis?
The disease may progress over several days or even weeks, consequently affected birds are often very thin or emaciated. The Trichomonas gallinae parasite is vulnerable to desiccation and cannot survive for long periods outside the host.
What causes trichomoniasis in birds?
Transmission is most likely to be through contaminated food or water, e.g. where a bird with difficulty swallowing regurgitates food that is then eaten by another individual. Trichomonas gallinae is a parasite of birds and does not pose a health risk to humans or their mammalian pets.
Are Greenfinches in decline?
The greenfinch has declined by 64 per cent in the last 23 years and shows no ‘no sign of slowing down’, according to the 2019 Breeding Bird Survey. Experts say the main cause of the decline is a parasite that causes a disease called the Trichomonas gallinae.
Can humans catch disease from birds?
Psittacosis is a disease caused by bacteria (Chylamydia psittaci) spread through the droppings and respiratory secretions of infected birds. People most commonly get psittacosis after exposure to pet birds, like parrots and cockatiels, and poultry, like turkeys or ducks.
What has happened to the greenfinches?
Greenfinch populations declined during the late 1970s and early 1980s, but increased dramatically during the 1990s. A recent decline in numbers has been linked to an outbreak of trichomonosis, a parasite-induced disease which prevents the birds from feeding properly.
