Kargalar Hakkındaki Yanlış Bilgi

Kargaların Ömrü nedir?

Karga

 

Kargalar Antik Yunan ve Roma’da uzun ömürlülüğün sembolü olmuştur. Plutarkhos’un Hesiodos’un kayıp bir eserinden aktardığına göre, karganın ömrü insan ömrünün dokuz katıdır (A chattering crow lives out nine generations of aged men,). Geyikler kargalardan dört kat fazla yaşarken, kuzgunların ömrü geyiklerinkinin üç katı kadardır.[4]

Gerçekte kargaların ömrü 20 yıl kadardır.[5][6] Ancak vahşi hayvanlar ve hastalıklar nedeniyle genellikle bundan birkaç yıl daha kısa yaşarlar.

Bilinen en yaşlı Amerikan kargası 29 yıl 6 ay yaşamıştır [4]. En yaşlı ikinci Amerikan kargası ise 14 yıl 7 ay kadar yaşamıştır [5]

İhtiyar karga öldü
Dünyanın en yaşlı evcil kargası olduğu iddia edilen Tata, 59 yaşında öldü. Tata yıllar önce yaralanarak uçma yetisini kaybedince hayvansever bir aile tarafından evcilleştirilmişti.

Doğada kargalar 10 yıl yaşarlar bu +/- 2 hatta 3 de olabilir (Dilling, 1988, Ontario Bird Banding Association Newsletter 22:2-3). Bilinen ikinci en yaşlı olan ise 14 yaşında ve 7 aylıktır (Clapp et. al., 1983, Journal of Field Ornithology, 54(2): 123 -137).

How long do crows live?

Most crows don’t even live a year, having died in the egg or as nestlings. In my study population of American Crows in Ithaca, New York, just about half of the nests succeed in producing young. Of the young I band in the nest a week before fledging, about half are alive and with their parents the next year. Of course some have disappeared and not died, but that’s a pretty good survival rate for birds anyway. Once they survive that first year they have a good chance of making it for several years more. None of my birds try to breed when they are one year old, and some are six years old and still helping their parents. Average age of first reproduction for females is 3.3 years, and males average 4.9 years. Breeders have about 93% yearly survival. My survival data (biased towards the short side by those that disappear) indicate that some crows should live to be 17 – 21 years old [note this is a change in the prediction from what I have had posted before Dec 1998, based on reanalysis of survival data]. The oldest known wild American Crow was 29 1/2 years old (see Dilling, 1988, Ontario Bird Banding Association Newsletter 33: 2-3.). The second oldest known, however, was only 14 years, 7 months (Clapp et al., 1983, Journal of Field Ornithology, 54(2): 123-137).

As of November 2010 we have 2, probably 3 crows that were banded as nestlings in 1993 that are still alive, making them currently 17 years and 7 months old. Here is a photo of one of them, AP HART93 when he was just 17. You can see that his colored and metal bands have fallen off, and the has only the remnants of his wing tags.

Şimdiye kadar kaydedilmiş doğadaki en fazla yaşamış karga ömrü 13 yıl 4 aydır.İnsan kontrolü altında 80 yıl yaşamış bir karga da kayıtlara geçmiştir. Ayrıca Londra’da bir merkezde (kuş yetiştirme merkezi gibi bir şey sanırım) yaşayan kargaların ortalama 44 yıl yaşadığı saptanmış. Ayrıca bu veriler de Corvus Corax türüne ait, diğer türler bu kadar uzun yaşamıyorlar.

Güzel bir kaynak olan ve her canlının ingilizce adını yazarak doğada ve korumalı yaşam ömrünü bulabildiğiniz bir site.

Sonuç olarak, aslında kargalar sanıldığı kadar uzun yaşamıyorlar. Bu kanı Yunan ve Roma mitolojisinden kalmıştır.
