Crows are exceedingly smart, timberdoodles are back and cardinals just may be nesting already. Those are some of the interesting email topics I have received recently.

Don from Laconia wrote to say he has observed some interesting behavior from crows that hang around his yard. When the crows find a piece of food that is too big or hard, they carry the food to a nearby puddle and dip the food into the water to soften it and make it more manageable.

It has long been known that crows and other corvids, such as ravens and blue jays, have a high degree of intelligence. There is a video on YouTube with close to 10 million views that shows an experiment with a crow figuring out how to access food from tubes using water displacement. The pieces of food are floating on water in a tube just out of reach of the crow’s beak. In a series of tests, the crow has to figure out how to raise the level of water enough to reach the food. The crow eventually aces all of the tests and gets to the food each time.
