“…Some of the earlier studies have been reviewed by Ware ( 1975 ). Ames and Mersereau ( 1964 ) and Ames ( 1966 ) reported on the status of the osprey along the Atlantic coast. Most populations were experiencing dramatic declines associated with poor hatching and fl edgling rates.…”

“…Henderson et al ( 1971 ) reported 0.85-3.27 ppm total DDT in fi sh collected from the Connecticut River in 1968 and 1969. In addition, Ames and Mersereau ( 1964 ) reported total DDT levels of 2.5-9.2 ppm in scraps of fi sh cast from osprey nests on Great Island near the mouth of the Connecticut River. Moreover, ospreys feeding in the Connecticut River estuary in 1967 were poisoned by dieldrin (Wiemeyer et al 1975 ).…”

“…Nest desertion in response to human activity, even if temporary, is often followed -sometimes immediatelyby predation of eggs or young (Anderson and Keith 1980;Deitz and Hines 1980;Fraser et al 1985;Datta and Pal 1993;Cott 1969cited in Liddle 1997. It can also result in exposure to lethal temperatures (Fraser et al 1985), eggs rolling from the nest as the startled parents leave (Ames and Mersereau 1964), young fleeing in panic and not re-uniting with parents (Anderson and Keith 1980), and depleted energy reserves of parents and young Temple 1986a, 1986b;Gabrielsen and Smith 1995). Anderson (1995) notes that most waterfowl form close cohesive groups with one or both parents, the disruption of which, by separation or death of a parent, can cause mortality of their offspring: the same would apply to many other birds and mammals.…”

Tourism based on free-ranging animals is economically important, but there are no comprehensive studies on the overall balance of its negative and positive effects on wildlife. However, there is a growing body of information on which we can draw for minimizing negative effects and enhancing positive ones. Major categories of negative effects include: direct injury and death; disruption of activities or increase in stress levels; and loss or modification of habitat. About half the published research literature on negative effects involves relatively conspicuous avian species, and there is a need for further research on other taxa. Major categories of positive effects include financial and practical contributions by tourists and tourism operators, economic incentives for wildlife conservation (acting through local communities, the tourism industry and governments) and environmental education. There is far less information on positive than on negative effects, and research is required to examine this quantitatively. However, the evidence suggests there is considerable unrealized potential for wildlife tourism to provide substantial conservation benefits.

“…The osprey was affected worldwide by extensive use of organochlorine (OC) pesticides, mainly related to the DDT group. Their populations have suffered local extinctions or experienced dramatic population decreases in areas where these pesticides were found at high concentrations (Ames and Mersereau 1964;Henny and Ogden 1970;Hickey and Anderson 1968;Postupalsky 1969). Thus, the osprey has been considered a good indicator of the effects of OC pesticides on biological systems.…”

We identified and quantified organochlorine (OC) pesticide residues in the plasma of 28 osprey (Pandion haliaetus) nestlings from a dense population in Laguna San Ignacio, a pristine area of Baja California Sur, Mexico, during the 2001 breeding season. Sixteen OC pesticides were identified and quantified. α-, β-, δ- and γ-hexachlorocyclohexane, heptaclor, heptachlor epoxide, endosulfan I and II, endosulfan-sulfate, p,p'-DDE, p,p'-DDD, aldrin, dieldrin, endrin, endrin aldehyde, and endrin ketone were the OCs found in the plasma of nestlings, ranging from 0.002 to 6.856 pg/μl (parts per billion). No differences were found in the concentration of pesticides between genders (P > 0.05). In our work, the concentrations detected in the plasma were lower than those reported to be a threat for the species and that affect the survival and reproduction of birds. The presence of OC pesticides in the remote Laguna San Ignacio osprey population is an indication of the ubiquitous nature of these contaminants. OCs are apparently able to travel long distances from their source to the study area. A significant relationship between hemoglobin and mean corpuscular hemoglobin concentrations and OC concentrations were found suggesting that a potential effect on the health of chicks may exist in this osprey population caused by the OC, e.g. anemia. The total proteins were positively correlated with α-BHC, endosulfan I, and p,p'-DDD. It has been suggested that OC also affects competitive interactions and population status over the long term in vertebrate species, and our results could be used as reference information for comparison with other more exposed osprey populations.
