We have sadly come to the end of our two weeks with you. Here are the answers to the questions we set in the first week.
Can you name three insects choughs love to eat?
Acceptable answers include ant larvae and eggs, dung beetles, cranefly larvae (leatherjackets), beetles, flies, worms.
Why are choughs also known as 'sea crows'?
Because they nest in sea caves or crevices and feed on coastal grassland habitat.
Apart from the chough what other bird species has Jersey Zoo helped save from extinction?
Mauritius pink pigeon, echo parakeet, Mauritius kestrel. Bonus points if you researched and also said Madagascar pochard or Galapagos mangrove finch
How do the choughs know when to arrive for their supplemental food?
The keeper blows a whistle. They have also learnt what time keepers feed them and stay around the aviary waiting for food.
Name one way in which staff monitor the choughs after they have been released?
Radio-tracking/observations of leg rings/health screening with feacal samples and observations/recording daily body weight.
How many of the released choughs are still flying free today?
This is a math question: there are 29 captive-bred released birds plus 5 wild-hathed birds = 34 choughs
Where do choughs nest in the wild and what do zoo keepers do to replicate this in the zoo?
They nest in sea caves and crevices. Keepers use wooden boxes designed to feel like a deep cavity.
How do keepers prevent chicks from imprinting on them when they hand-feed?
They wear black gloves and feed the chicks using red tweezers to look like a chough face.
Why is bracken bad for choughs and other insect eating birds?
It stops light getting to the soil to provide the right conditions for insect populations to survive which the birds feed on. It also locks the birds from getting to the soil to feed.
Can you list three ways sheep help choughs?
1) grazing to restore habitat 2) dung provides a source of food 3) wool to line chough nests.
Where else in the UK does grazing benefit chough populations?
