Do not worry too much if your homing pigeons get lost while out on a flight – this happens from time to time. They will tend to group with another flock of pigeons or will be seen sitting on roofs or other areas looking disorientated but will continue on their journey home. Your homing pigeon should have a leg band with home information on it. Pigeons are not caught unless they are ill or weak from ranging -- you can simply pick these birds up or catch them with a bird net. Some lost pigeons are dehydrated and hungry and may need time to replenish their strength.
Reach gently for the bird. Kneel down and offer an outstretched hand with bird seed to entice the pigeon. Place a dish of water before the bird (dip a finger and splash the water to show the pigeon it is in the bowl).
Watch to see if the pigeon is tired and dehydrated. Look for signs including ruffled feathers and a hunched-up appearance. Note that ill or weak pigeons are easily approachable.
Wait for the bird to recover. Birds that are very weak, hunched up or not eating or drinking in a few hours need immediate veterinary attention. Release a recovered and alert pigeon in a safe and open area and it should reorient and fly home on its own.
