We further propose that the restricted but geographically complex distributions of birds-of-paradise species may be a consequence of the promiscuous breeding system.Birds-of-paradise (Paradisaeidae) are renowned for their complex courtships and diverse male plumages with highly elongated and elaborate feathers.Thus the idea that sexual selection could generate high speciation rates and rapid changes in sexual ornamentations is not supported by our birds-of-paradise data.Potentially, hybridization and long generation times in polygynous male birds-of-paradise have constrained morphological diversification and speciation, but external ecological factors on New Guinea may also have allowed the birds-of-paradise to develop and maintain magnificent male plumages.The phylogenetic results confirm some traditionally recognized relationships but also suggest novel ones.Furthermore, we find that species pairs are geographically more closely linked than previously assumed.We were both far each other when we first started chatting, he was in England and I was working in Saudi Riyadh at that time.I finished my contract and returned to the Philippines where we both met face to face for the first time and there were sparks!

The degree of sexual dimorphism found in the majority of species of birds-of-paradise (cryptically coloured females while males have spectacular ornamented plumages and elaborate courtship displays) is one of the most prominent avian examples of sexual selection.

The barrels have a wonderful, almost stepped breech which is not uncommon on Fraser double rifles and even early small bore Rigby double rifles.

For any David Mc Kay Brown aficionado who fancies a tussle with the big game of Africa, this would make a great addition to the armoury.

The name David Mc Kay Brown should need no introduction to readers of this blog.

Scotlands premier gun and rifle maker, David is still building guns at his factory in the village of Bothwell, near Glasgow, Scotland.

The family has accordingly been used as a case-study in several significant evolutionary and biogeographical syntheses.
