Acoustic Identification bats of Antigua and Barbuda

Family

Natalidae

Scientific name

Natalus stramineus Gray, 1838

Taxonomy follows Simmons and Cirranello (2022)

Call shape

Calls shapes are FM broadband, short duration and very high frequency

Calls sequence shown in full spectrum (Kaleidoscope 4.3.2 and SonoBat 4.2.2)

All zero-crossing images are displayed in AnalookW as a compressed view with empty space removed to display the call sequence pattern.  The X-axis is in milliseconds and the Y-axis is a logarithmic scale in kHz.

See notes for important considerations.

    Notes

    Calls of Natalids are generally very quiet and relatively high frequency.
    As high frequencies attenuate rapidly with distance  they will not be recorded from any appreciable distance.


    Therefore, not suitable candidates for acoustic monitoring.
