regard this a friendly reminder not to antagonise Crow : consort to a2011 studyinProceedings of the Royal Society B , American crows remember the faces of hoi polloi who wrong them , and engage other bird to set on the wrongdoer .
When it come to intelligence , birds get no respect . For a foresighted time , scientists bear birds were stupid because their brains had significant differences from ours . But recent studies on doll brains and power are putting those fallacy in their place . research worker have found sophisticated behavior in birds fromfinchesandpigeonstoAntarctic gulls . But there ’s one group of birds that consistently amazes : crows and Corvus corax .
Within the last 10 class we ’ve learned that crows can make , store , andcare for tools . They can reckon and practice self - restraint . They canuse baitto catch fish . They can certainlyplay . And , the author of theRoyal Proceedingsstudy say , they can entertain some serious grudges .
research worker at the University of Washington ’s School of Forest Resources bought two masks that looked like human side . A caveman - looking masquerade party was indicate the “ dangerous ” masquerade party , while aDick Cheneymask was “ indifferent . ” They then visited wild line-shooting at five sites around Seattle . At each web site , the person wearing the caveman mask would approach the Crow , trap a few , banded their legs , and localize them free — an experience the bird did not enjoy . As soon as the researcher allow them go , the birds began shout at their capturer with a rough , aggressive cry called “ lambast . ”
The audio of conflict attract more birds , which join in scolding and attack the researcher , even though they ’d never suffer . “ The mob of two to 15 birds hounds us , sometimes dive from the sky to within a few meters or less . This pursuit lasts about 100 meters ( 328 foot ) as we take the air off , ” crow expert John MarzlufftoldDiscovery News .
The Dick Cheney masque did not elicit a response .
Marzluff and his co-worker then traveled to other crow territories . The raft of the caveman masque caused an immediate ruckus among these crows — even though none of them had ever been caught or banded . Crows up to a mile off from the original site had heard about this no - good caveman hombre , and they knew he was hassle when he walk in .
The score did n’t wear off , either . Marzluff say replication trips in the caveman mask provoked the same unfriendly reception , even five age by and by . Hetold Discovery News , " Individual crow that are adults can be 15 - 40 years in the state of nature ( most exit when new , but those that make it to maturity can know a long clip ) and they probably call back important affiliation they have form for much of their life . "
These association are n’t all negative . An 8 - year - old girl , also in Seattle , made news last year when her kin give away that local crows had moderately muchmade her their queen .
