At World Bird Sanctuary,
enrichment is a key part of our birds’ lives.
Enrichment prevents the birds from getting bored, keeps them entertained
and fosters natural abilities that they would use in the wild. Enrichment can range from a cereal box
to a new game or behavior; it doesn’t have to be complex, just different.
Something as simple as a head of lettuce to tear apart is enrichment
Last summer I presented a
bird show at Stone Zoo in Boston, MA, and when
you are away at shows like I was, enrichment items are a little more difficult
to come by, so you have to get creative.
The good news is when you all live and work together like my staff and I
did in Boston, in one house, you buy a lot of
groceries, which leads to a lot of recycling. Pretty much every paper board product that passed through
our house ended up as a crow or raven toy. Boxes, toilet paper tubes, ice cream
tubs, shipping boxes, tissue boxes, paper towel tubes, Chinese takeout
containers (no metal), to-go coffee cups (cardboard only), drink caddies; you
name it, we probably stuffed newspaper and food in it to give to a crow or a
raven.
Enrichment is not just
about objects though, it is also about timing. Giving a bird the same thing over and over again or doing
the same behavior over and over again is less enrichment and more routine; it
is no longer as stimulating. We
had an issue this summer with Othello, our African Pied Crow and Hugnin our
White Necked Raven not wanting to do their enrichment behaviors, since they did
them every day that winter. Once
we invented new behaviors and found new enrichment toys for them to play with (thrift
stores are an enrichment enthusiast’s best
friend), they were more excited.
Enrichment is not just for
crows or ravens, although their higher intelligence does demand more
stimulating activities. Many of
our raptors got enrichment devices this summer as well.
Osiris our Egyptian
vulture sometimes received her extra food in a soda box or collapsible box,
both of which required her to use her long, narrow beak to find her food--much
like she would in the wild.

Clark, the Bald Eagle
would get something different every night; boxes, bags, old towels, blue jeans
tied in knots, sisal rope tied in knots, and even heads of lettuce. Clark loved to rip, tear and
nibble…kind of like a puppy. If he didn’t have anything to play with, he made
his own toys…out of his jesses and anklets. Since it was no fun for us--or
Clark---to replace his anklets, we always made sure that Clark had something to
play with every night.
Jesses and anklets were not an approved "toy"
Clark was
not the only one who loved the heads of lettuce. Mia the Spectacled Owl liked to tear them into shreds
and Peabody a European tawny owl liked to eat them, after tearing them into
tiny shreds (the lettuce is not bad for this carnivore).
Even when the raptors are
not working, we like to give them fun things every now and then, like a chicken
egg or crayfish. Sometimes we go
all out and carve pumpkins for Dorothy the Andean Condor and stuff them with
food.

Enrichment can be simple,
like a box stuffed with food or complex like designing a new game for a
crow. Regardless of the
complexity, as long as it keeps the bird stimulated and all items or enrichment
training is safe for the bird, it is like surprising the bird with a trip to
the amusement park.
Bet you’ll never look at a
cereal box the same way again… I never have!
