You will often discover that birds are picking very small insects from decks and other woodwork around your house; they do the same with trees and any other structure that might hold the bugs. We see them often on our decks and they usually pick a little bit and then move on, perhaps just checking to see if there is anything edible there. These rascals also love hummingbird or oriole nectar, sunflower seeds and of course suet in winter.
We have discovered many species that will head straight for the nectar for orioles or hummingbirds and also plunge their beaks eagerly into the grape jam bowls orioles love. Birds will eat a greater variety than you might think.
We have found they do not like limburger cheese, hot dogs, or Makers Mark bourbon. I am thankful for that.
Tysons chicken tender, Top sirloin steak, pork chop, burgers seasoned to taste - crispy crowns, tutor tots, fries - beer batter shore lunch Walleye, Crappie all better than deep fryer, oven or gas grill. Just do potato first & keep hot in oven at 250. Even Spam is better than pan fryed but if your under 40 you may not have a clue about Spam.
Yes spray it, or wipe it down with an oiled paper towel before you use it. I use a little ball of aluminum foil to scrub them after the cook, but while they are still warm. They make disposable grill topper grates that are handy too when you are cooking something that is going to be really messy.
