In Goshawk-Eurasian Nature Reserve, 30 percent of the birds are hawks, and 40 percent of the non-hawks are paddyfield-warblers. If there are 25 percent as many kingfishers as paddyfield-warblers in the reserve, and the number of white storks is 10 percent more than the number of kingfishers, then what percent of the birds in the nature reserve are not hawks, paddyfield-warblers, kingfishers, or white storks?
