What´s the difference between Golden Eagles and White-tailed Eagles?

Here is a general overview. You can compare also other species with this tool https://www.birdid.no/bird/eBook.php?co ... cieID=1413

Territories (Norway/Scotland)
  • “White‐tailed and Golden Eagles appear to partition nesting habitat in the west of Scotland by altitude. This corresponds with behaviour in western Norway and with the situation described in historical accounts of nest‐sites in western Scotland prior to extinction of White‐tailed Eagles.” Read more: Comparative nest habitat characteristics of sympatric White-tailed Haliaeetus albicilla and Golden Eagles Aquila chrysaetos in western Scotland. Richard J. Evans , James Pearce‐Higgins , D. Philip Whitfield , Justin R. Grant , Alison MacLennan & Robin ReidBird Study (2010) 57, 473–482. https://www.tandfonline.com/doi/abs/10. ... 010.489317
Diet (data from several European countries)
  • Breeding season diets of sympatric White-tailed Eagles and Golden Eagles in Scotland: no evidence for competitive effects. D. Philip Whitfield, Mick Marquiss, Robin Reid, Justin Grant, Ruth Tingay & Richard J. Evans (2012) Breeding, Bird Study, 60:1, 67-76, https://www.tandfonline.com/doi/full/10 ... ccess=true
  • WtE diet, several sources: See e.g. doc #40-44 viewtopic.php?f=46&t=233 and doc #23, 29 viewtopic.php?f=46&t=240
  • Food items brought to the Estonian WTE nest 2016 viewtopic.php?f=18&t=825
  • New study: "Prey selection by Danish Golden Eagles Aquila chrysaetos during the breeding seasons 2005-2016". Jan Tøttrup Nielsen collected a total of 1640 prey items (pellets and remains) in and around five nests in the northern part of Jutland. He identified 73 prey species (birds: 50, mammals: 22; one reptile species). According to Tøttrup Nielsen, the most frequently registered species were common pheasant, wood pigeon, crow, European hare, roe deer, water vole, mallard, domestic chicken and black-headed gull.

It's that time of year again :2thumbsup:

How does an egg develop from the time it is laid to the time it hatches?
For White-tailed Eagle eggs it takes about 38 days to hatch, chicken eggs have a 21 day incubation period - very similar things happen in the eggs of eagles and chickens.

About 53 years ago, Tom Rauber saw the last pair of bald eagles in New York state. Amazing story about an enthusiastic amateur ornithologist and a species brought back from the brink of extinction. Read the article by Gwendolyn Craig here

At that location "Fiener Bruch", (It is quite near to my home location :D ) probably is the following not a current problem for other reasons.
Fact is: where number of WTE increases, not only great bustards are endangered, LSE are also displaced.

Biker, I'm not sure I understand what you meant by “at Fiener Bruch probably is the following not a current problem for other reasons”. Could you please explain it a little more?

A bird population that almost does not exist anymore for many reasons can' t be displaced anymore by another species which number increases.
Otherwise it is unfortunately so: the more WtEs, all the less LSE, (they will be displaced)
