Chipmunks and Safflower Seeds

 

Several types of birds that like to eat seed scattered on our deck.

Several types of birds that like to eat seed scattered on our deck.

We face a problem shared with many people who want to feed birds. Some birds prefer to eat seeds that have been scattered on the ground rather than eating them from an elevated bird feeder. Basically, we like to feed birds like the ones pictured in the panel above. So we scatter bird food on our deck, which is outside the living room windows.

We do feed lots of birds on the deck. However, here is the big problem with this approach. We have lots of Grey Squirrels, and they are very good at vacuuming up all the bird seed from the deck. Sunflower seeds are their favorite, and they eat those first. In addition, they chase off the birds. Now we don’t mind feeding the squirrels. They are very interesting creatures to observe. But we would like to devise a way to feed those birds that prefer to eat from ground level.

One of our friends suggested that we feed safflower seeds rather than sunflower seeds. According to our friend, squirrels would not eat safflower seeds, but birds would. So we bought some safflower seeds to give it a try.

I made a ring of safflower seeds on the deck, and stood by to watch the proceedings. Sure enough, it seemed to work! Squirrels would not eat the safflower seeds. This photograph shows a squirrel eating a sunflower seed right next to the ring of safflower seeds.

However, we failed to reckon with a third party that entered the scene to upset our plans. There is another contender for seed strewn on the deck. This is one of several chipmunks that regularly visit our deck in search of food,

This photograph shows a squirrel and a chipmunk next to the ring of safflower seeds. The squirrel is looking for a sunflower seed. The chipmunk is busy filling its cheek pouches with safflower seeds. Our chipmunks are never seen to eat any seeds (including sunflower seeds) on the deck; they inevitably load up their cheek pouches and carry them back to their burrows.

This chipmunk set itself the chore of carrying all the safflower seeds away. It made repeated trips back and forth to the safflower seeds on the deck.

The panel above shows the gradual diminution of the ring of safflower seeds after repeated trips by the chipmunk. Now, I have to emphasize that we never, in fact, saw the chipmunk eat any safflower seeds; all were carried away to its burrow. However, I presume that these seeds were stored up for future consumption, and not used to make a beanbag chair or something.

It was surprising to me that chipmunks and squirrels, which are fairly closely related, would differ so much in their taste for safflower seeds. I do not know the basis for squirrels distaste for safflower seeds, but it is clearly not shared by our chipmunks.
