If you do not own a bird, you may not know this, but birds love to get wet. This is especially so, I suspect, with parrot species like lovebirds.
At least once a day, if not more, I take a spray bottle and offer our pair of lovebirds a gentle mist. This activity offers no end of enjoyment for both the birds and we human members of the family. It is funny to watch them react as they stand joyfully in the mist, turning their bodies and moving their heads around so that we don't miss a spot, shaking off the excess. Then when they are good and wet, there is the hilarious spectacle of wet birds. Their plumage becomes puffy, seeming to grow another 50% in bulk by magic, and their head plumage forms a pattern which looks like they have their "hair" gel-spiked. I like to call this the "wet bird hairstyle".
Clean, happy birds and happy humans. It's a good combination.
