Arguably the most remote and understudied of the four godwit species, they breed in largely remote near coastal bogs of Alaska and Canada before migrating to the very south of South America, primarily along the Argentinian Coast. This bird was a very off course vagrant having somehow found its way to the UK, where less than 10 individuals have ever been recorded.

Weight: 33-52g  /  Length: 20-25cm  /  Wingspan: 30-35cm

A widespread resident of Southern and Central Asia, although not present in much of mainland South East Asia or Borneo.  They are a fairly visually diverse species with some species having a typical shrike "bandit mask" while some subspecies have much more vivid colours and the black extends into more towards being a full "cap". This bird on the Gloucestershire/Oxfordshire border is only the third ever reported in the UK, thought fascinatingly the second arrived just a week prior and their stays overlapped, a bizarre coincidence for such a rare species!

I feel there are few who would argue that the Resplendent Quetzal is one of the most beautiful bird species on earth, with the males having long flowing irridescent tails that give them a mythic quality. Indeed, they were associated with the feathered serpent deity Quetzalcoatl of Mesoamerican myth and their plumes, taken from live birds which were then released due to laws preventing their killing, were used by rulers and nobility of certain Mezoamerican cultures as a symbol of wealth and power as part of elaborate headdresses and clothes.

An extremely distinctive curiousity of a bird - the Magnificent Frigatebird is the largest, most famous and widespread of the frigatebirds. Perhaps best known for the males possessing a bright red inflatable throat balloon that they use for mating displays. They also are one of the fastest birds in the world capable of moving up to 153km/h. Their feeding habits are a mix of catching fish from the water and using their speed, size and power to kleptoparasitise other seabirds, forging them to regurgitate their own catches.
