birds of prey - the 4 classes
- hawks (long winged)
e.g. harris hawk - falcons (short winged)
e.g. peregrine falcon - eagles
e.g. golden eagle - owls
e.g. barn owl
falconry - what is it
the keeping of falcons (or other birds of prey) and training them to hunt wild animals
sport?
(legalities)
licenses - when are they needed/not needed?
- no license needed to own/fly CAPTIVE BRED birds of prey
- illegal to take birds of prey FROM WILD and keep without Defra license , unless receiving treatment from vet/person registered to treat and INTENTION OF RELEASE
(legalities)
name an act that is responsible for protection and management of wild animals:
what this act states
why?
Wildlife and Countryside Act 1981
species listed in schedule 9 = non-native = if captured legally cannot be released OR ALLOWED TO ESCAPE
illegal to take eggs from nest > inform Defra
risk/may cause damage to native birds/plants
(legalities)
Wildlife and Countryside Act 1981 - what happens to a lot of ‘schedule 9’ birds when they are captured?
often euthanised
not ethical (welfare) to keep these birds of prey in captivity/confinement for rest of lives
(legalities)
Wildlife and Countryside Act 1981 - what is the exception for some ‘schedule 9’ birds?
the general license
‘schedule 9’ animals can be re-released after period of rehabilitation under this license
(legalities)
Wildlife and Countryside Act 1981 - NAME the ‘schedule 9’ birds which the general license applies to:
4
barn owl
northern goshawk
red kite
white-tailed eagle
(also applies to other mammals - above are birds of prey only)
common welfare problems in captive birds of prey
no license to fly/own CAPTIVE BRED =
- poor housing
- lack of exercise
- incorrect diet
- lack of social interaction (w humans and other BOPs)
flight weight - define
ideal weight for flying – lowest weight that allows optimal performance
CAST - 3 definitions
1- method of holding bird for examination ‘
2- regurgitate a pellet
3- 2 or more birds flown together
cast off - define
released from fist
casting - define
indigestible part of diet
foot/footing/being footed
bird strikes with its feet
imping - what is it
replacement of damaged feathers by gluing new tip onto broken feather
= precision in flying
mutes - define
droppings/faeces
manned (to man)
tamed and used to humans (not necessarily imprinted)
mews
building that bird kept/trained in
hood
leather cap that covers bird face, to calm
husbandry - the 2 basic systems for BOPs
1) tethered on blocks/perches (usually temp)
2) aviaries (‘free lofting’) - still need weathering no to protect from wind/rain
2 examples of injuries from inadequate husbandry:
sand impactions (from eating?)
bumblefoot (pododermatitis)
2 perch types
bow
block
3 perch surfaces
- astroturf
(easy to clean, some argue too sharp on feet) - nylon rope
(smooth = does not distribute weight/pressure well = pressure sores) - natural materials e.g. bark
(not as easy to clean)
diet - what body parts to raptors eat?
entire carcass
regurgitate bones/feather/fur (indigestible)
diet - what to/not to feed?
- do not feed pure muscle (not balanced diet)
- do not feed same each day (mix chicks/rodents/rabbits etc.)
Ca:P ratio of 2:1 growing birds, 1.5:1 adults (most important dietary factor)
