Besides the pale tail edging, what other identifiers separate T. verticalis?

Answer

Gray head, pale breast, and bright yellow belly

While the tail feature linked to *verticalis* is crucial, field identification relies on a combination of traits that distinguish *T. verticalis* from its close relatives. These primary visual identifiers include a distinct gray coloration on the head, a pale area on the breast, and a bright yellow coloration across the belly region. These consistent color patterns, combined with the tail mark, provide the necessary contrast for accurate species separation.
