Energetic costs of bill heat exchange demonstrate contributions to thermoregulation at high temperatures in toco toucans (Ramphastos toco)
J. Chaves, G. J. Tattersall, D. Andrade
This study measures the metabolic rate of toco toucans with and without bill insulation to assess the bill's role in thermoregulation at high temperatures, finding it significantly contributes to heat dissipation above the thermal neutral zone.
