When I was shooting this gull I certainly hadn't planned on catching him regurgitating his food, but there it is in all its glory. Yeesh.

Breeding behaviour

Where possible, the birds excavate a nesting burrow into the soil. Sometimes they will make use of Manx shearwater or rabbit burrows. Where burrowing is not possible, the birds nest under boulders or in cracks and cavities in cliffs.

The birds defend the nesting site and its immediate surround, and use it in subsequent years. Puffins lay only a single egg, in late April or early May. Both parents incubate it for 36-45 days, and they share the feeding duties until the chick is ready to fledge.

The fledging period is very variable, ranging from 34 to 60 days, depending on the area and year.

Adult birds desert their young shortly before they are ready to leave the nest. The timing of the breeding in puffin colonies is highly synchronised, and so the departure of all adults takes place within a few days.

The young birds leave their nest burrow and make their way to the sea, normally under cover of darkness to avoid predators. In some colonies, for instance in Iceland, nearby bright lights confuse the young birds, which then fly into the light and end up on city streets.

Puffins usually reach breeding age at 5-6 years old, and often live for 20 years.

The white-fronted tern is the most common tern on the New Zealand coastline, at times occurring in flocks of many hundreds or even thousands of birds. It is mainly a marine species that is seldom found far from the coast. The name ‘white-fronted’ refers to the ‘frons’ or forehead, where a thin strip of white separates the black cap from the black bill. Most other ‘capped’ terns, including the black-fronted tern, have black caps that reach the bill when in breeding plumage. The scientific name striata refers to the finely-barred (striated) dorsal plumage of recently fledged white-fronted terns, as the original description and name was based on a juvenile bird painted by William Ellis, surgeon’s second mate on the Discovery, on Captain Cook’s third visit to New Zealand - www.nzbirdsonline.org.nz

Sometimes bird behaviour is hard to explain. This little scrap of feathers was being repeatedly chased and attacked by an adult of the same species which kept flying in from some distance away. It took the combined efforts of both parents to drive the attacker off. I wondered whether the rest of the brood had already been killed by the invader.

Tit for tat, do unto others, one good turn deserves another. These are only some of the familiar expressions which articulate the belief that #reciprocity is a basic principle of #social_interactions
