Middle American screech owl

The Middle American screech owl (Megascops guatemalae), also known as the Guatemalan screech owl, is a species of owl in the family Strigidae and is usually found in forests and dense second growth. The taxonomy of this species and the vermiculated screech owl can be confusing. When split, the name vermiculated screech owl (M. vermiculatus) is used for the population from eastern Nicaragua to Panama, and this species is found from northern Mexico to Nicaragua. When conspecific, the English name vermiculated screech owl is used, but M. guatemalae is used for the scientific name since it is older.[2] The "guatemalae" larger conspecific group usually includes the foothill screech owl, M. roraimae and the Choco screech owl, M. centralis.

The tail is relatively long for an owl, the underside has conspicuous longitudinal stripes and some horizontal stripes. Its face is surrounded by a dark feather edge and it has relatively short ear tufts. The eyes are yellow. The beak is pale olive-greenish in color.

  • M. g. fuscus (R. T. Moore & J. L. Peters, 1939)
  • M. g. guatemalae (Sharpe, 1875)
  • M. g. hastatus Ridgway, 1887
gollark: In general.
gollark: Or the peak can be in different places.
gollark: Or it can skew left/right.
gollark: Yes.
gollark: These are continuous distributions, so there's technically an infinitesimal probability that it's any particular value (handwavily) but you can integrate over a region of it to determine the probability that a sample falls within that region.
