Silver level titles (equivalent to the White bridging book band) use sentences with two or three clauses and the length of the texts extends to around. In this story, a wildlife ranger cares for a penguin injured in such a disaster, until it is able to be released back into its natural environment. In fact, the predicted population persistence increased up to nearly six times after the application of the action plan.

Oil spills at sea result in many birds, fish and sea animals being destroyed. Accordingly, the fecundity recovered to values close to those prior to decline (from 0.6 to 1.3 young/pair) and the sex ratio was balanced again (from 81% to 48% males). The lower adult mortality resulted in a lower population turnover and thus in an increasing average age of breeders (proportion of non-adult plumage decreased from 21.3% to 8.9%). After implementing the plan, the annual adult mortality decreased from 12% in the declining period to 2.1% during the recovery period. Likewise, the population was reinforced with the release of young eagles (mainly females) by hacking techniques. Supplementary feeding throughout the year with live wild rabbits was undertaken to prevent breeders from foraging outside the National Park and therefore reducing adult mortality by poisoning. In face of the imminent extinction, an urgent multi-action conservation plan was implemented in 2004. The high adult mortality due to poisoning was the main cause of the decline, decreasing fecundity and biasing the offspring sex ratio to males due to a higher proportion of non-adult breeders in the population. The population of Doñana National Park (south-western Spain) suffered a dramatic decline from 1990 on, after a long period of stability. The Spanish imperial eagle ( Aquila adalberti) is one of the most endangered raptors in the world.
