Oil-Soaked Birds Saved: Hsus Participates In Historic Bird Rescue Apr 1978

Oil-Soaked Birds Saved: Hsus Participates In Historic Bird Rescue

Close Up Reports

As the world watched the black tide of crude oil from the Amoco Cadiz devastate bird life along the French coast, HSUS staffer Guy Hodge was reporting to Congress about efforts to save oil-soaked birds in a recent Chesapeake Bay oil spill. A barge (ATC- 133) carrying nearly 500,000 gallons of crude had run aground south of the Maryland-Virginia border. Some of its cargo spilled into this North American waterfowl wintering area.

Together with HSUS cruelty investigator Phil Steward, Hodge had assisted in the most successful on-site bird rescue operation in history. One out of every three rescued birds was …

Quantitative Analyses Of The Ontogeny Of Predatory Behaviour In Coyotes, Canis Latrans, Louis E. Vincent, Marc Bekoff Feb 1978

Quantitative Analyses Of The Ontogeny Of Predatory Behaviour In Coyotes, Canis Latrans, Louis E. Vincent, Marc Bekoff

Ethology Collection

Four infant coyotes (Canis latrans) were studied in order to describe quantitatively the development of predatory behaviour. Our results indicated that prior play and agonistic experience had virtually no effect on later predatory success. Also, there was no relationship between an individual's social rank and its prey-killing ability. Latency to kill was shortened when animals were tested in, pair and hunger level was not related to latency to kill. The results are discussed with respect to current 'functionalist' theories of play behaviour and Leyhausen's concept of the relative hierarchy of moods. The practice theory of play should be reconsidered in …


Social Behavior In A Group Of Captive Bobcats : A Study In The Sociability Of Felids, Lon W. House Jan 1978

Social Behavior In A Group Of Captive Bobcats : A Study In The Sociability Of Felids, Lon W. House

Dissertations and Theses

A group of four captive bobcats (Felis rufus), two males and two females, was observed for 102.67 hours over the period of one year. A pilot study was conducted consisting of a minimum of three separate observations for each daylight hour. The remaining observations were concentrated during the early morning hours immediately after feeding, the time of maximum activity and social interaction.


Hsus Spotlights Circus Cruelty Aug 1977

Hsus Spotlights Circus Cruelty

Close Up Reports

Who can deny the sense of excitement the young and the young-at-heart feel when the circus comes to town? The sounds, smells, and attractions create a fantasy world where everything is fun.

But is it all good clean fun? Evidence in recent years suggests quite the contrary. The worst problems seem to be with the smaller circuses. In the past year, The HSUS has assisted several local societies investigating cruelty to animals in traveling circuses, rescued elephants and lions abandoned by a circus, and signed three complaints against one of the largest of today's small big tops.

According to Frantz …

Mammalian Dispersal And The Ontogeny Of Individual Behavioral Phenotypes, Marc Bekoff Jul 1977

Mammalian Dispersal And The Ontogeny Of Individual Behavioral Phenotypes, Marc Bekoff

Ethology Collection

Explanations of dispersal mechanisms in mammals that have stressed the importance of aggression by dominant (?) individuals as the immediate cause of the dispersal of less aggressive (more subordinate?) individuals are insufficient for explaining recent data collected on a variety of mammals. In fact, avoidance of social interaction at the time of dispersal is more characteristic of some species in which individuals emigrate. Studies that have investigated genetic correlates of dispersal in rodent populations that undergo regular cycles are few and have not provided any "causative" explanations. In various canids and rodents, behavioral interactions at the time of dispersal do …

Struggle To Save Dolphins Continuing

Close Up Reports

The Humane Society of the United States has initiated a nationwide boycott of a tuna products until real progress is made in reducing the needless slaughter of porpoises in tuna nets.

In the Spring of 1976, HSUS first asked its members to refrain from buying tuna because of the high porpoise mortality and the tuna industry's unwillingness to adopt any research porpoise-saving procedures. Recently, HSUS Program Coordinator Patricia Forkan called for a nationwide boycott of tuna.

Learned Helplessness Through Observation: Failure To Escape Traumatic Shock As A Result Of Observing A Helpless Situation, Donald Jary Apr 1977

Learned Helplessness Through Observation: Failure To Escape Traumatic Shock As A Result Of Observing A Helpless Situation, Donald Jary

Masters Theses & Specialist Projects

Twenty naïve male and female hooded rats were randomly divided into four groups of five subjects each. The Observe Helpless group was allowed to observe Helpless subjects receive signaled, inescapable electric shock, after which they were tested for effective escape response acquisition. Subjects in the Observe Naïve group were allowed to observe Naïve subjects being given escape-avoidance training using signaled presentations of electric shock, after which the Observe Helpless group was given similar escape-avoidance training. Results indicate that there were significant differences in the acquisition of effective escape responses between the Observe Helpless group and the other two groups. Possible …


Hsus Raids Save Suffering Dogs Feb 1977

Hsus Raids Save Suffering Dogs

Close Up Reports

In two raids separated by more than 1,000 miles, HSUS investigators seized several hundred suffering dogs, arranged for their care, and spurred legal action against the collector and breeder. Describing the two places as "cesspools", Frantz Dantzler, chief HSUS investigator, said "These two places were chosen for raids because they are typical of the many substandard puppy mills and kennels found in rural out-of-the-way America."

Both the Roseboom, New York Kennel and the Columbus, Kansas puppy mill had similar violations of humane standards and everyday common sense. Most of the seized animals had advanced cases of mange. Many animals had …


Social Communication In Canids: Evidence For The Evolution Of A Stereotyped Mammalian Display, Marc Bekoff Jan 1977

Social Communication In Canids: Evidence For The Evolution Of A Stereotyped Mammalian Display, Marc Bekoff

Ethology Collection

The variability in the duration and form of the canid play bow was studied in infant coyotes, wolves, wolf-dog hybrids, beagles, and adult free-ranging dogs. Both duration and form showed marked stereotypy. It appears that the role of this context-specific social signal in the communication of play intention has been fostered by selection for "morphological" stereotypy.
