There are nearly 20,000 known bee species in the world, and 4,000 of them are native to the United States (an estimated 400 additional native bee species remain to be identified in the U.S.). From the tiny and solitary Perdita minima, known as the world’s smallest bee, to the large carpenter bee, to the brilliant blue of the mason bee; native bees...
Bird Bands
Most bird bands are made of an aluminum alloy and have unique numbers engraved. These numbers can wear off with time to the point that one or more numbers become illegible. The time that it takes for a bird band number to wear off depends on the habits of that bird species and the amount of time that it spends in the water. For instance, a band on...

Affected birds have difficulty feeding and preening, and...
