Editing Razorbill (section)

=== Feeding ===
Razorbills dive deep into the sea using their semi-folded wings and their streamlined bodies to propel themselves toward their prey. They keep their feet spread. While diving, they rarely stay in groups but rather spread out to feed. The majority of their feeding occurs at a depth of {{cvt|25|m|ft|round=5}} but they have the ability to dive up to {{cvt|120|m|ft|round=5}} below the surface.<ref name=Piatt/> During a single dive, an individual can capture and swallow many schooling fish, depending on their size. Razorbills spend approximately 44% of their time foraging at sea.<ref name=Thaxter/>

When feeding their young, they generally deliver small loads. Adults will mainly feed only one fish to their chick with high feeding deliveries at dawn and decreased feeding 4 hours before dark.<ref name=Conder/> Females will generally feed their chicks more frequently than males.<ref name=Thaxter/> They may fly more than {{cvt|100|km|mi|-1}} out to sea to feed when during egg incubation, but when provisioning the young, they forage closer to the nesting grounds, some {{cvt|12|km|mi|frac=2}} away, and often in shallower water.<ref name=lilliendahl2003/>
