116.Recovery dynamics and viability of the white-tailed eagle (Haliaeetus albicilla) in Germany

Justine Sulawa, Alexandre Robert, Ulrich Köppen, Peter Hauff, Oliver Krone

Understanding the effect of protection measures on recovery of endangered populations is crucial for assessing the efficiency of management plans. Following the ban of DDT, PCB and other detrimental chemicals in the 1970s, the German white-tailed eagle population recovered rapidly. Using nest monitoring data, dead recovery data and population dynamics models, we examined both short and long-term viabilities of the population. (...)

123.Carbofuran poisoning incidents in the Czech Republic

“The number of the reported cases of poisoning and the detected baits has significantly increased over the last 10 years. At the same time poisoning has become increasingly serious, especially with regard to the number of the poisoned eagles. Approximately 65 couples of this critically endangered species nest in the Czech Republic; in some years almost 10 eagles were poisoned with carbofuran confirmed.”

Carbofuran – key facts
-What is carbofuran?
-How does carbofuran kill?
-Why do we deal with poisoning?
-How to recognise poison bait?
-How to recognise poisoned animal?
-What to do if you find poisoned bait or poisoned animal?

126.Collision risk in white-tailed eagles. Modelling collision risk using vantage point observations in Smøla wind-power plant

"Foreword: In July 2010 NINA was contacted by Chris Marden from SSE Renewables, Scotland. He asked whether we could analyze the vantage point data from Smøla to derive avoidance rates for white-tailed eagles using the so-called ‘Band’ collision risk model. SSE Renewables wished to receive an increased insight into these avoidance rates for use in a pre-construction collision risk assessment for white-tailed eagles concerning the development of a wind-power plant in Scotland. The report presents the results from this modelling exercise."

127.Young White-tailed Eagle near Halle, Eastern Germany, returned into “the wild” (July 2009).
The rings of this bird could be read in Poland at December 22nd 2009


Summary

June 30th, 2009: A Family from Brachstedt, a village in the district Saalekreis in Saxony-Anhalt, reported to the Halle Zoo a big raptor which had caught a hen and was still on site, sitting on a barn. The bird could be identified by an ornithologist as a young White-tailed Eagle. At July 2nd the exhausted and emaciated youngster tried his luck again in a chicken-run in Brachstedt, but got caught up in the netting. He was captured and brought to Halle Zoo.

A fortnight later, the eagle - meanwhile ringed* and fully recovered - was released near Burgliebenau, in an area with a lot of waterfowl. He flew without any problems (leaving aside that he has been attacked several times by a marsh harrier).

At December 22nd 2009 the rings of this eagle could be read at Niezgoda, Zmigrod (Dolnoslaskie), Poland – 346 kilometres east of the place where he has been returned into “the wild”. (See the map in the German article to find Brachstedt/Halle Zoo/Burgliebenau/Niezgoda.)

*Ringing: left a Hiddenseering (Hiddensee = German isle in the Baltic Sea/Mecklenburg-Western Pomerania), golden anodised, AA8555; right a white ring with black inscription AD74 (see the picture in the article)

134.Common breeding of Buzzard (Buteo buteo) and White-tailed Eagle (Haliaeetus albicilla) in a nest of White-tailed Eagle

By Jörg Kasper

There is proof of twelve White-tailed Eagle breeding pairs in the Lower Silesian region (Germany) in 2002. The breeding of two more pairs has been assumed.

Members of the Professional Group Ornithologie Niesky watched from a larger distance, but with good observation conditions, an unusual event in a nest: a White-tailed Eagle pair raised up a Buzzard together with their own chick. Both young birds fledged.*

The eagle pair occupied the nesting site end of February/early March 2002. On March 7th the eagles started breeding. One of them was present at the nest constantly now. Probably on April 16th one eaglet hatched, but not until May 1st it could be said definitely that only one chick was in the nest. At May 25th an uncommon trouble was noticed there. After one of the adults brought fresh food, the eaglet ate by itself besides the other adult bird. Suddely the bright head of a second young bird in downy plumage became visible. It was fed immediately by the adult eagle.

During the next days it was very difficult to observe this chick, because it almost always ducked down deep into the nest. But on June 10th it could be clearly identified as Buzzard (Buteo buteo). As of June 24th his wing exercises has been observed. On June 29th it was reported that the young Buzzard sat at a spruce about 30 metres next to the nest. Several times a day he flew back to the nest to get his food. The maiden flight of the young White-tailed Eagle was noticed on July 3rd ; both young birds came back to the nest constantly, and on this day both were around the adults, begging for food.

Since July 4th, the Buzzard was no longer seen, while the young Eagle stayed along with his parents near the nesting site until mid-November.

How the Buzzard got into the eagle´s nest will probably remain a mistery; nevertheless it´s not the first known case of common breading. Some young living Buzzards in a White-tailed Eagle nest were discovered in Poland in occasion of ringing the eagle offspring (Mrugasiewicz 1984, Hussong 1990 with pictures).

Peter Hauff, since many years engaged in the ringing of eagles in Mecklenburg-Western Pommerania, sent this note to the editorial team: “I can report such a case from the last year. While ringing about six week old eagles we found the headless body of a some days old bird of prey in the nest. Obviously the bird died just a short time before. O. Krone (Berlin) identified it by gene analysis as a young Buzzard. Now to my thought about this theme, after reading your article: The nesting time of both species is well known. Both young birds fledged at the same time – that´s surely the most important fact for further considerations. Nesting time White-tailed Eagles: twelve weeks; Buzzards: seven or eight weeks. So it can be excluded that both had hatched at the same time in this nest. A further breeding of the smaller Buzzard egg for three or four weeks can be excluded, too.

135. The idea that captured chicks from other raptor nests in exceptional cases could survive in White-tailed Eagles nests may sound perhaps a bit fantastic, but it seems to be plausible for me. The eagles may raise them up with their own chicks, if they beg for food like the young eagles do. I would take this for the probable cause…”

This assumption is shared by J. Frölich und W. Baumgart (personal message to S. Ernst), bird of prey experts which have been asked concerning this case. Baumgart wrote additional: “Such cases can almost be observed at single pairs, who specialised in nest predation.” W. Spank reported another case to me. He is aware of a White-tailed Eagle pair in Upper Lusatia (Eastern Germany), which used to bring young Buzzards in their nest in several years. In this nest, located at Milkeler Heide/Raudener Teiche, the carcass remains of a one week old Buzzard were found by the side of two eagle chicks at May 5th, 1996. In 2000, early June, there was one young eagle in the nest, and with him – still alive – a Buzzard, about ten days old. (W. Gleichner moved this bird in a buzzard nest.) June 2001: again the remains of a Buzzard besides two young eagles. On June 24th (2002) Buzzard feathers were found in the nest, where also in this year two eagles had hatched. So probably this eagle pair at Milkener Heide specialised in nest predation (see note above, W. Baumgart).

With regard to this, I would like to mention also the Black-breasted Buzzard or Black-breasted Kite (Hamirostra melanosternon), the third largest bird of prey in Australia. This species carries sometimes living prey in its nest, in the majority of cases chicks of the Australian Kestrel/Nankeen Kestrel (Falco cenchroides) und Brown Falcon (F. berigora). Occasionally these chicks are reared by Black-breasted Buzzard pairs with their own brood. (J. Cupper 1977, L. Cupper 1995).

Thanks for sharing observation results to Friedhard Förster (Förstgen), Ernst-Hartmann Gottschlich (Horka), Werner Klauke (Dauban) und Wilfried Spank (Boxberg); for encouraging discussions and for provide academic literature to Joachim Frölich (Grüna) and Dr. Wolfgang Baumgart (Berlin); for constructive comments concerning the preparation of the manuscript to Peter Hauff (Neu-Wandrum) and Stephan Ernst (Klingenthal).

* The local German broadcasting corporation MDR (Mitteldeutscher Rundfunk) sent at July 2nd 2002 in “Sachsenspiegel” a TV report about this case (original title: „Tierliebe zwischen Sachsens größtem heimischen Raubvogel und einem kleinen Verwandten“).
