Baked Potato Pizza Baked potatoes are all-American. You've had them so many different ways. I decided to put them on pizza, Guy says. This potato pizza includes all the fixings-bacon, cheese, sour cream, and chives.
White-throated Sparrows sing a pretty, thin whistle that sounds like Oh-sweet-canada-canada or Old-Sam-Peabody-Peabody. The whistles are even but typically move slightly up or down in pitch by the second or third note. The whole song lasts about 4 seconds.
Birds make tons of different sounds: chirps, rattles, whistles, trills, croaks, drumming, and many many more. But how do birds make these sounds? Well there are two categories of sounds: vocal and non-vocal sounds. Vocal sounds are made by a special organ only birds possess: the syrinx. The syrinx is located at the very top of the birds' windpipe. The air that comes in through the windpipe causes thin membranes to vibrate and produce sound.
