Diving heart rates in Adélie penguins (Pygoscelis adeliae)
Abstract l. In Antarctica, two Adélie penguins were implanted with heart rate (HR) transmitters and released in their breeding colony where they resumed incubation. 2. HR while at rest and lying in the colony were 67 and 77 beats per min (bpm), respectively. 3. For diving experiments, the birds were...
