Czech Republic: The still mysterious death of eagle Viktor

Image
Viktor was found dead in South Bohemia in October. According to the police, a necropsy performed on the country´s only transmitter fitted White-tailed eagle revealed there was no criminality involved with the death of the animal. Libor Šejna with the Makově Wildlife Center rescued and released the eagle at the beginning of this year. The web portal Jižní Čechy Teď reported Šejna said he had no possibility to verify the necropsy results - perhaps a heart attack caused the death of the raptor. He also pointed out that Viktor was young, well fed and in excellent physical condition.

How long do White-tailed Eagles live?

The oldest known ringed eagle in Schleswig Holstein (Germany) is 29 years old. According to a newspaper article, Rolf Zietz managed to take a picture of the bird recently. Report from the same region: „The maximum ages of breeding birds, all estimated on the basis of annual collections of individually identifiable moulted feathers, were 32 (2), 33 (2), 34 and 36 years.” (Struwe-Juhl, B. 2002). White-tailed Eagle longevity records from Finland, Norway and Estonia can be found here http://www.looduskalender.ee/en/node/9327

Update, March 2017: White-tailed Eagle "Kuba" died at 33. The bird lived in a flight pen in the city of Miedzyzdroje/ http://www.wolinpn.pl/index.php?page=45 Woliński National Park, Poland. 29 March 2017 http://radioszczecin.pl/1,351717,leciwy ... &si=1&sp=1
Update, May 2017: Britain´s oldest white-tailed sea eagles feared dead. “Lochan and Misty, who are both believed to be 37 years old, have not been seen since last summer.” 6 May 2017 https://www.thetimes.co.uk/article/olde ... -6mgm8fdtk

Update on Caeltra and interesting observation: Post-Fledging movements of White-tailed Eagles in Ireland and Norway

“Most major movements of released WTSEs that we know of, especially the satellite tagged birds, and young Irish-bred eagles have been north rather than any other direction. This is also the case in Norway where the large number of satellite tagged young WTSEs show northward movements on dispersing from the nest area. Thus there appears to be a hard-wired genetic predisposition to disperse north of Irish birds, whether of Norwegian origin or parentage but Irish bred.” Source: Golden Eagle Trust at Facebook, 16 November 2015 https://www.facebook.com/Golden-Eagle-T ... 4/?fref=nf "In long-lived raptors with delayed maturity, the period between fledging and settlement on a breeding site may take several years and is poorly understood."

Image Book Tip: Population Ecology of Raptors, Ian Newton

About the book:
“Dr Newton's book is concerned with all aspects of population regulation in diurnal birds of prey, their social behaviour, dispersion, numbers, movements, breeding and mortality. He has drawn on his own studies in Scotland and on material and investigations worldwide to produce an authoritative and stimulating synthesis of current thinking and research on the ecological problems of the Falconiformes. He also deals in detail with the effects of pesticides and other pollutants on these birds, and with their scientific management and conservation.” (Source: Bloomsbury Publishing 2010) Preview available via Google Books.

New report on raptor persecution & poisoning in Northern Ireland published today

“In the five years from 2009 to 2013 there were 30 illegal poisoning or persecution incidents, affecting 33 protected raptors (birds of prey), confirmed in Northern Ireland according to a report published today by the Partnership for Action against Wildlife Crime Northern Ireland (PAWNI).

The most frequent casualty was the buzzard (19 birds) followed by the recently re-introduced red kite (7 birds) and then peregrine falcons (4 birds). Other raptor species that were recorded included a white-tailed eagle, a golden eagle, sparrowhawk and a merlin.”

According to Northern German Broadcasting (NDR), an unknown person cut down illegally a large poplar tree that housed a pair of White-tailed Eagles. The area near Mildstedt is not easily accessible to the general public. A 3.500 Euro reward is being offered by the WWF and the municipality of Südermarsch for information leading to the charging of those responsible for destroying the nest.

The database project was launched five years ago. Since then it has grown quite a bit. Image

Ireland: Golden Eagle Trust update on the seven month old Caeltra

“Interesting that she has headed south in the opposite direction from Aoibheall, the 2014 Mountshannon chick, and the first of our birds to show such a southerly movement.” (One month ago the team reported: “Most major movements of released WTSEs that we know of, especially the satellite tagged birds, and young Irish-bred eagles have been north rather than any other direction. This is also the case in Norway where the large number of satellite tagged young WTSEs show northward movements on dispersing from the nest area.” See above, 16 November.)
