Now that we’ve looked at the five basic pitch patterns<\/a> and the four basic song patterns<\/a>, let’s explore a couple of ways to extend and combine the vocabulary we’ve learned.<\/p>\n

Changes in speed<\/h4>\n

One of the basic questions we ask of any bird sound is, “are the notes slow enough to count, or too fast to count”?\u00a0 Sometimes, the answer is both<\/strong>.<\/p>\n

Some bird sounds change in speed. If the elements in a series are more closely spaced on the spectrogram as you move from left to right, then they are growing more closely spaced in time, which means that the series accelerates<\/strong>. If the elements grow farther apart, the series decelerates<\/strong>.<\/p>\n

\"\"<\/a><\/p>\n

Here are a couple of examples. The song of the Wrentit is a series of notes that accelerates into a trill, while the drum of a Yellow-bellied Sapsucker starts as a trill of tapping notes, and slows into a series.<\/p>\n\n\n\n
