Lesser Spotted Eagle

• Almost the entire world population passes through two very narrow migration bottlenecks: the Bosphorus and the Jordan valley, where tens of thousands of birds are counted within a few days in September.
• It lays two eggs but almost always only the first chick survives: the elder systematically kills the younger within the first few days, an obligate siblicide that makes the real breeding rate half the apparent one.
