Bird feeders and bird watching can provide a lot of exercise!
The supporting facts:
1) You must go back and forth to your seed bucket in the garage to the feeders, often - not only do the birds eat a lot, but those pesky squirrels take their share, too, so refilling is frequent!
2) Running back and forth into the house to get your bird book to identify what you just saw or heard is also something that keeps you moving. How often do you hear a new "chirp", and strain to see where the source is perched? You spot that beauty, taking in the shape of the beak, the coloring, the size...! As you run to your old faithful bird book, with so many pages folded over referencing past sightings, and you repeat to yourself, "short yellow beak, white belly, black tail, etc., etc., etc.
3) You return to the scene of the bird sightings, holding as still as you can... almost in a yoga-like pose, hoping again for that new find, or another, to arrive.
Now that I think of it, there could be a whole new industry based on the fitness of birding!
What do you think? Do you get a lot of enjoyment - and exercise - from your bird feeders?
