In Hanover, New Hampshire, where elms were sprayed with DDT, 151 dead birds were found; 10 dead birds were found in Norwich, Vermont, where no DDT was used. Chemical analyses of dead birds, observation of symptoms of DDT poisoning, and a population decline after spraying all indicate severe mortality among certain species in Hanover. 

Bird Mortality Following DDT Spray for Dutch Elm Disease

Feeding habits suggest that some birds acquired the toxicant by eating living insects carrying DDT, presenting the paradox of survival of the intended DDT victims, and death, instead, of insectivorous birds.

Some effects of Dutch elm disease on nesting farmland birds

This review of nest record and census data attempts to assess the impact of Dutch elm disease on arboreal bird species and see what are the alternatives to elms.

Persistence of DDT in Wild Populations of Small Mammals

Data is presented of pesticide residues from small mammals covering a period of 9 years after single applications of DDT applied to forests at a rate of 0.89 kg/hectare (1 pound/acre).

Effects of DDT treatments applied for tsetse fly control on white‐browed sparrow‐weaver (Plocepasser mahali) populations in NW Zimbabwe

Summary Colony density and size, and numbers of white-browed sparrow-weavers were investigated in Colophospermum mopane-Julbernardia globiflora woodland treated from nought to five times with DDT

DDT Residues in an East Coast Estuary: A Case of Biological Concentration of a Persistent Insecticide

High concentrations of DDT in soil of an extensive salt marsh on the south shore of Long Island suggest that many natural populations in this area are now being affected, possibly limited, by DDT residues.

Pesticides and Bird Populations

It is concluded that the major impacts of current biocide uses on birds are in the Third World countries, where restrictions are uneven and where effects are largely undocumented.

Occurrence and consequences of DDT residues in woodland birds following tsetse fly spraying operations in NW Zimbabwe

Populations of the wood-hoopoe and chat declined over 2-3 years in sprayed areas by about 90%, but no differences attributable to spraying were detected in the other species, and DDT residue concentrations 1-3 months after treatment reflected feeding site more than diet.

High Mortality of a Population of Cowbirds Wintering at Columbus, Ohio

An investigation of the cause of death in a population of Eastern Cowbirds that formed a part of a large blackbird roost on The Ohio State University Farm during the winter of 1963-64 finds that causes of death may be associated with the lowering of their body temperature, enhanced by bathing in streams containing detergents.

The race to prevent the extinction of South Asian vultures

It may be some years before diclofenac is removed from the vultures' food supply, and captive populations of three vulture species have been established to provide sources of birds for future reintroduction programmes.


Abstract Residue analysis of forest soils sprayed once at 1 lb/acre showed little breakdown of DDT through 9 years after application. In the absence of appreciable downward trend, residue persistence



Initial songbird mortality following a Dutch Elm disease control program.

Three methods have been subsequently used which have been thought to reduce this mortality of songbirds following field applications of DDT during the insect-control programs.

Persistence of DDT in Soils of Heavily Sprayed Forest Stands

Soils from DDT-sprayed forest stands in New Brunswick and Maine contained DDT residues. The residues increased in successive samplings between 1958 and 1961, although no new spray was applied. The

Wildlife effects of DDT dust used for tick control on a Texas prairie

A large scale field triai of the value of DDT in control of the Lone Star tick (Amblyomma americanum) was made by the U. S. Army and the U. S. Department of Agriculture in the summer of 1947. A 10

Effects on wildlife of DDT used for control of Dutch elm disease

Results would appear to be applicable to the Dutch elm disease problem as it exists elsewhere in the nation and this report summarizes results of the first summer's work on the problem.

Insecticides to Prevent the Emergence of Scolytus multistriatus

Emulsions of four insecticides were tested for their effectiveness in preventing emergence of the smaller European elm bark beetle, Scolytus multistriatus (Marsh.), and Lindane was most effective, followed by dieldrin and DDT in reducing emergence.

Effects of DDT on bird population of scrub forest

The present study details the effects on a bird population of a five-pound-per-acre application of DDT where the nature of the cover was such that little "screening out" of the spray occurred, and approximated conditions that might be met in comparable control attempts in some agricultural situations.

Effects on forest birds of DDT used for gypsy moth control in Pennsylvania

Between April 18 and June 28, 1945, the birds populations on three tracts near Scranton, Lackawanna County, Pennsylvania were determined by repeated, systematic census trips. One tract ("Mile

Poisoning by DDT: Relation between Clinical Signs and Concentration in Rat Brain

The severity of signs of poisoning in rats after a single dose of DDT is directly proportional to the concentration of the compound in their brains. The concentrations associated with death after one

Disappearance and visibility of quail remains

To determine the rate of disappearance of loose feathers, 40 assortments were placed in rows at Union Springs in 1957 and tests were conducted on two areas, one at Gadsden, Alabama, and another at Buna.
