Lear’s Macaw – Ornithology


I assumed it could be good to go to a hen that we don’t hear a lot about: Lear’s Macaw.

Of 380 species of parrots worldwide, 19 are labeled as macaws, a particular group of huge, colourful birds. Inhabiting the tropical forests of South America, macaws differ from different parrots with their comparatively bigger beaks, lengthy tails and a light-colored cheek patch. Macaws are additionally identified for his or her beaks that are specialised for nut consuming, significantly within the case of Lear’s Macaw, the Licuri nut. The higher beak is hooked and the decrease beak suits snugly towards the higher, creating highly effective leverage to crack open nuts and is equipped with sensory nerve endings. Like all parrots macaws have appreciable beak dexterity, permitting the birds to maneuver the nuts into the very best place for cracking. Though the one-inch Licuri palm nut is so arduous it could take a hen a minute or so to crack, the birds could eat as many as 350 nuts and day, the nut comprising 95% of the Lear’s Macaw food regimen.

The genus Anodorhynchys accommodates two stunning blue parrots, the Hyacinth Macaw and Lear’s Macaw. The Hyacinth Macaw is extra widespread than Lear’s, having been identified to science since 1790, whereas Lear’s was solely found in within the mid-19th century and misplaced for numerous years till it was rediscovered in 1978 and thus is much less well-known. Essentially the most distinctive function of Lear’s Macaw is its intense cobalt-blue plumage overlaying many of the physique. The naked patch of pores and skin across the eyes is a pale yellowish coloration, surrounded by a feathered ring of blue. The bottom of the lengthy tapering tail is darkish blue lightening to a light-weight blue on the tip. Its heavy black invoice can also be distinctive. The Hyacinth Macaw is nearly equivalent to Lear’s however is a few third longer and heavier, darker in coloration, and the biggest of the flying parrot species.

The restricted habitat of Lear’s Macaw is principally as a result of their nesting habits. The birds stay in a semi-arid area of scrublands and thorny vegetation in Northeast Brazil referred to as the Caatinga, South America’s largest seasonally dry tropical forest.  They make the most of small ledges on limestone cliffs to excavate holes for nesting and resting. Their heavy dependence on Licuri palm nuts as a meals supply contributes to their restricted distribution because the palm forest have been decreased as farmers destroy them to plant agricultural crops or for livestock grazing. The birds have additionally been topic to unlawful trying to find the pet parrot commerce. Though they’re presently endangered and are one of many rarest parrots on this planet, their standing was beforehand thought of “critically endangered”. Their inhabitants has been rising within the twenty-first century, numbering maybe 1400 birds. Solely a few third of the grownup birds breed annually, so inhabitants progress is gradual.

Of all of the 380 species of parrots on this planet, 116 are listed as weak, endangered, or critically endangered by the ICUN (Worldwide Union for the Conservation of Nature) Pink Record.
