The voucher must be used on the selected date and within operating hours; Invalid after expiration — Safe Interaction Guidelines — As part of the commitment and concern for your safety, please read and acknowledge the following safety, interaction, and feeding guidelines that apply within the flight aviary.• Please remove all loose items from your person, including earrings, hats, watches, and sunglasses, and stow them safely away until outside the aviary • If a bird lands on your shoulder please do not make any sudden moves or loud noises. It may scare the bird, which may dig in with its claws and flap its wings in order to keep its balance. Once their curiosity is satisfied, the birds will usually fly off by themselves. If a bird is unusually "sticky" and has worn out its welcome, seek assistance from the staff • Umbrellas are available at reception for those guests who would rather admire the birds from afar. Please use them responsibly. Umbrellas can scare birds and be hazardous to other visitors• Any outstretched finger pointed at a bird's head is usually an open invitation for a bite. Help to care for the birds. Please do not bring any food or drink into the flight aviary. Items can be left at reception if required • In the interest of hygiene, it is always a good idea to wash your hands thoroughly after interacting with wildlife. Handwash gel is available at reception and at the toilets
