Beware of Burdock

Burdock may be an inconvenience to humans, but it can be a death trap for hummingbirds. Reports of hummingbirds hopelessly snared in burdock burrs aren't frequent, but they are regular each summer.

The common burdock (Arctium minus) is considered a weed by most people, in part because it is not a native plant, but was brought here from Europe, and now grows wild from coast to coast. Those familiar with the plant, which can grow to six feet, know it mostly because of the tenacious burrs it produces. They are fairly large, spiky, and cling to almost anything they touch. It is how the plant spreads its seeds, but anyone who has walked through a burdock patch has had the experience of trying to detach the pesky burrs without puncturing fingers.

Burdock may be an inconvenience to humans, but it can be a death trap for hummingbirds. Reports of hummingbirds hopelessly snared in burdock burrs aren't frequent, but they are regular each summer.

The problem for the hummingbirds is that they are not strong enough to pull the burrs lose from the plants, and they become trapped, "Velcroed" in place. In thrashing about to free themselves, the birds only become more entangled. If burdock has invaded your yard or property, this is one plant you'd be wise to remove.

  • I understand that the ducks' blood vessel arrangement in their feet is to provide the benefits of the counter-current heat exchanger mechanism; returning cold venous blood from the feet is warmed by the descending warm arterial blood, preventing excess heat loss by the feet and avoiding cold blood from chilling the body. This means that the feet are cold, not warm.

  • I have the same situation. The feeder is attached to the middle of a large picture window that goes ceiling to floor w/ no ledge or sill for animals to climb or balance. Yet every morning all the sunflower seeds have been cracked open and hulls left. Any ideas what it is?

  • I have a bird feeder that sticks to my window and I've been hearing noises against the window at night right now its going on. But whatever it is it is aware of me. And when I get to window it leaves.I can't imagine a squirrel or mouse or possom being able to get at it. ...So as I was reading this article im to assume no bird eats at night. Or no birds will eat at night. Why is that? Then im also thinking of a sinereo that could a lost confused bird eat at night. This eating thing is watching meI turn out the light go there noise dissappears..Thank you.
