Administer the prepared fluid(room temp) from the pipette, cotton bud or small artist brush. Place a small drop [say, 0.02 ml] on to the side of the swifts beak/mouth, avoiding the nostrils at the top of the beak!
You may have to repeat this process a few times to allow the bird to recover for a few minutes between each drop. Observe if the bird swallows before administering more drops.
Swallowing can be induced by gently stroking the throat!
The Common Swift population in the UK is suffering a serious decline but veterinary nurses can help!
