The animal on the cover of RaphaelJS is a Nile Valley Sunbird (Hedydipna metallica),a colorful passerine (perching) bird that is commonly found in the Middle East andnorthern Africa. Every February, the male Sunbird grows “nuptial plumage,” which arevibrantly colored feathers that he displays to impress the females of the species.
The nuptial plumage tends to consist of glossy green/blue/violet feathers on the backand sides with a brilliant yellow underbelly and one or two long tail streamers. This isin stark opposition to the normal appearance of males and the year-round appearanceof females: a musty brown body with a cream and dull-yellow colored belly and shorttail. The mating display occurs for days, with the male being careful to display his plumageto the female and gain her attention through short calls that grow louder as theday continues. The male’s bright plumage starts to fade after two to three months, andthen the two sexes become almost physically indistinguishable.
Sunbirds require good sources of nectar, and are similar to hummingbirds in theirfeeding behaviors—they are quite small (only 15cm long at their largest) so they candart and flicker around very quickly, and even have a hummingbird-like beak that isbest suited to trumpet-shaped flowers. Although the Nile Valley Sunbird population hasnot been officially quantified, it has been designated as stable because of the frequencyof sightings and the birds’ large range of habitat. Sunbirds are best known for beingfrequent visitors to the famous walled gardens of Oman, Yemen, Saudi Arabia, andEgypt.
