Birds of prey

The environmental impact of PCNs has not been extensively investigated and PCNs are not routinely measured in analytical studies of extracts from environmental samples. However, PCNs have been identified in birds of prey in Britain (69) and The Netherlands (70), in a drainage ditch in Florida, and in sediments from San Francisco Bay (71). [Pg.67]

The detrimental effect of organochlorine pesticides on reproductive success in birds of prey is well established following the crash of some populations during the 1950s and 1960s. Links have been established with the DDT metabolite, DDE, the cyclodiene pesticides and Although many raptor species... [Pg.67]

Although eggshell thinning attributable to DDE exposure has occurred in birds in the UK, the lethal and siiblethal effects of the cyclodiene pesticides aldrin, dieldrin and heptachlor are also believed to have contributed to the population effects, particularly in the case of the sparrowhawk and peregrine falcon. Following the withdrawal of DDT and the cyclodienes from use in the UK, Europe and North America, bird of prey populations that were severely affected have shown partial or complete recovery. ... [Pg.67]

In a puzzling phenomenon, the insecticide did not stay where it was sprayed. In the five years between DDT s release for civilian use in 1945 and 1950, DDT used against flies in cow barns reappeared in cows milk. DDT was linked to fish-eating birds of prey that produced fewer or no young. Princeton, New Jersey, used 4.5 pounds of DDT per Dutch elm tree per year, and scientists found DDT in the tissue of dead birds and a nestling survival rate of only 44 percent. [Pg.162]

Predation (e.g. by foxes and birds of prey) may also be a serious cause of mortality in free-range husbandry. Foxes can be kept away with a solid fence, which can be supplemented by an electric fence. Birds of prey are not a big problem for poultry houses that are closed at night and free of holes. However, keeping birds of prey such as the hawks away is not easy, especially for farms surrounded by forest or in a landscape with a lot of trees. In such situations, low structures should be provided as hiding places for the hens. [Pg.134]

Interaction effects of mercury with other contaminants, such as herbicides and pesticides, could intensify hazards to avian populations (Mullins et al. 1977). For example, a striking parallel exists between levels of Hg and of DDT and its metabolites in birds of prey, suggesting the existence of common ecotoxicological mechanisms (Delbeke et al. 1984 Wiemeyer et al. 1984) additional research is clearly needed. [Pg.412]

Results show that for Cd (i) birds of prey are always more sensitive that beasts of prey and (ii) bioaccumulation is lowest in the food chain Soil —> worm —> bird/mammal. The latter food chain to birds of prey is by far the most critical pathway for Cd exposure, leading to very low critical limits for soils (approximately 0.1 ppm,... [Pg.67]

Many of these wild places and conditions are quite unintended outcomes of our own actions. Urban people are constantly making incidental natures, interacting with nonhuman species to create environmental outcomes of startling complexity. The lesser kestrel, a bird of prey currently on the brink of extinction, thrives in some cities of the Middle East, where it nests in clay roof tiles in areas of urban growth, just as the recovery of the peregrine falcon, a threatened species in the United states, is partly predicated on its New York City... [Pg.12]

The other group of dream animals met under Yage are the jungle birds, which are large birds of prey. [Pg.111]

Mosca is the heir The parasite flaunts his knowledge of their wrongdoing to the birds of prey and they leave in despair. Disguised as a police officer, Volpone follows them to taunt them further. [Pg.3]

In the tradition of the beast fable, the name Voltore characterizes the gull as a bird of prey. The vulture hovers outside the rooms of the fox waiting for his victim to die. [Pg.6]

Though the play is set in Italy, Jonson has already satirized London Puritanism. In the last sequence, he prepares us for the English tourist Sir Politic Would-be. Sir Pol suggests the poll parrot, and the English fools are bumbling and ineffectual mimics of the fools of the main plot. Lady Pol is a burlesque of the three birds of prey. [Pg.9]

During this sequence, it is important to visualize Mosca s movements. The gadfly darts from one bird of prey to the other, telling each that he alone shall inherit Volpone s wealth. He is not above calling each a fool to the others. Each of the three—Voltore, Corbaccio, and Corvino—plays a precarious part in Mosca s scheming. [Pg.24]

The vulture is one of the three birds of prey that circle around the fox, greedy and full of expectation. He is a lawyer and consequently has a weakness for wills. He uses his legal knowledge to advocate injustice in order to possess Volpone s fortune. Mosca wisely fools this gull by employing the advocate s own tactics that is, he tells Voltore the biggest lie and documents it with elements of well-known facts. [Pg.35]

The raven is the last of the greedy trio, a peacock proud of his beauty, Celia. This bird of prey is an exceedingly jealous husband who guards his wife with great care. Nonetheless, his greed persuades him to demand that Yolpone cuckold him When at last he discovers the error of his ways, he is too proud to reveal his foolish vanity. The paramount character quality of the three divergent birds of prey is their love and desire to possess money. [Pg.36]
