Do you ever get so excited about something that your whole face start out to turn red-faced ? Well , it seems that blue - and - yellow macaws do the same matter , allot to newfangled enquiry — though the precise reason they go crimson in the face is still unknown .
This should n’t come as a surprise to those who handle parrots on a regular basis , but it ’s the first step in a line of sketch that could identify just what macaw are trying to commune by acting this way .
“ It ’s about clock time somebody studied this , ” parrot expert and comparative psychologist Irene Pepperberg , who was n’t involved with the new study , secernate Gizmodo . “ It ’s exculpated these behaviors mean something , otherwise the birds would n’t engross in them . ”
written report writer Aline Bertin , an ethologist at the University of Tours in France , say she first heard about these blushing macaws from a zoo employee they ’d been working with for other inquiry . She was surprised when she see it for herself .
“ We witnessed these very rapid changes in skin color when the birds were storm by sudden events , or when their familiar caretaker approached or talked to them , ” Bertin order Gizmodo . “ It was very amazing for us to see this . ”
Bertin and her colleagues want to interpret why the bird blush , so they set up an experiment . They observed five drab - and - white-livered macaws that were raised in captivity in a Gallic zoo as their intimate caretakers either looked at and talked to them , or stand in the elbow room and dismiss them .
The skirt blushed and also rumple the feather on their head importantly more often when the caretakers engaged with them , according to thestudypublished Wednesday in PLOS ONE .
The fact that macaw blush to communicate is n’t surprising — parrot are outrageously smart and emotional birds that can reckon , tally and take off , and make and use tool . It ’s only natural that they have a wide-cut range of behaviors to evince their deep cognitive and aroused capability .
“ Parrots are considered to have primate - corresponding cognitive capacities and are thus mainly studied for their intelligence operation and their vocal communication capability , ” Bertin said . “ But far less is known about their immanent feelings and their capacity to intercommunicate their emotions . ”
Other snort blush , too . Some vulture do so when competing for food as a sign of hostility , and thecrested caracarablushes when it is aroused or stressed .
Researchers were very conservative about interpreting the meaning of the macaws ’ crimson behavior , since the sample size was so small . Pepperberg also note that the birds used in the study were all quite young — none had get hold of sexual due date , which might play a part in how or why they blush .
Still , Pepperberg said the study is a necessary first step in examine this behavior . It ’s useful to bonk if blushing does point sexual drawing card or aggression , for example .
“ If this is an belligerent response , then people who are handling these wench need to be mindful so they can plow them decently and back off , ” Pepperberg told Gizmodo . “ If birds are inappropriately treating the caretakers as sexual object , imprinting on humans , it ’s bad for preservation because they would n’t copulate with other raspberry . ”
Bertin plans to continue this line of sketch and identify exactly why blue-blooded - and - chickenhearted macaw blush . She want to study more macaws and observe them in their lifelike habitat . “ Plenty remain to be done , ” she say .
