Code:
birdnames="duck sparrow hawk"
read -p "Enter name of a bird   " name
if [[ " ${birdnames} " ==  *" ${name// } "* ]]; then
  echo "Yes, that is a bird."
else
  echo "That is not a bird."
fi

--
Or with a bash 4 associative array :

Code:
birdnames=(duck sparrow hawk "horned bill")
declare -A bird
for i in "${birdnames[@]}";
do
  bird[$i]=1
done

read -p "Enter name of a bird   " name
if [[ ${bird[$name]} ]]; then
  echo "Yes, that is a bird."
else
  echo "That is not a bird."
fi

or

Code:
birdnames=(duck sparrow hawk "horned bill")
declare -A bird
for i in "${birdnames[@]}";
do
  bird[$i]=
done

read -p "Enter name of a bird   " name
if [[ ${bird[$name]+1} ]]; then
  echo "Yes, that is a bird."
else
  echo "That is not a bird."
fi

or

Code:
declare -A bird
bird=([duck]= [sparrow]= [hawk]= [horned bill]=)

read -p "Enter name of a bird   " name
if [[ ${bird[$name]+1} ]]; then
  echo "Yes, that is a bird."
else
  echo "That is not a bird."
fi
