This year 23 young Eastern Imperial Eagles hatched in Bulgaria. There is hope for a few more chicks because of replacement clutches for some pairs.
According to the BSPB, for Bulgaria this means 1.4 chicks for a breeding pair in Bulgaria in 2010.
This year, only 16 pairs breed. In 2009 there were 18 pairs breeding. This may be due to an increased mortality in winter and early in the breeding season.
