SAINT HELENA PETREL
Оглавление– They are known to attack other birds, either beating them to death or drowning them. This applies especially to juvenile birds and chicks.
– Petrels produce stomach oil which they can either spray out as a defensive measure or can be regurgitated as an energy-rich food for chicks or for themselves during long flights.
– Like some other seabird species, Giant Petrels secrete a saline solution from a nasal passage in order to rid their bodies of the excess salt they swallow while feeding.
