  • A two-sample t-test can be used to determine whether the trend in observations of the Gray Catbird is the same as the trend in observations of Aves. Is this species just as common, as a proportion of all observations, as it once was? The answer is yes, changes in observation rate of this species do not significantly differ from changes in observation rate of its Class.

Three species of mimids to compare: Brown Thrasher, Northern Mockingbird, and Gray Catbird. All sound similar, but are easily distinguished. Thrashers generally repeat phrases twice, then move on to the next phrase. Mockingbirds repeat phrases 3-7 times before moving on to the next phrase, while catbirds do not generally repeat phrases.
