Chapter I. Field ethology – Conducting behavioral observations in the Budapest Zoo

Péter Pongrácz

1. 1. OBJECTIVES

This practical is about how to conduct basic observational studies on free moving animals. Students have to use their knowledge about the theory of ethological description of behaviour, the concept of ethogram and the most widely used methods of behavioural research. In the Budapest Zoo the students participate on a brief theoretical introduction, and then they can choose their subjects freely from among the numerous species available in the Zoo. The practical offers a wide array of possible methods and research questions, as each species shows more or less different behaviour and activity patterns.

The main goal of this practical is to provide a model of a full ethological study, beginning with the pilot observations and asking the proper research question, following with the data collection and analysis, and ending with writing a report and drawing conclusions from the results.

2. 2.INTRODUCTION

2.1. 2.1 The design of a scientific research study

Data collection is not the first step of the scientific research. Ideally, each study (which can either be observational or experimental) starts with establishing a proper research paradigm, or more simply, a research question. A new study’s question can be derived from a previous research work, but it can also originate from an accidental or planned observation or pilot study as well.

The first ‘official’ step of an investigation is forming the research question. The next step is to choose or develop suitable methods, which will enable us to collect the necessary data to answer the question. For choosing the appropriate method one will need to know well enough the circumstances and the subjects of the study, and it is also very useful if we know some of the related researches, which were published earlier on the similar topic. In other words, the methodological planning of a study requires a throughout practical and theoretical knowledge from the scientists.

Knowing our question and the outline of the methods we will use for answering it, it is worth to enumerate those hypotheses, which are basically the possible outcomes (answers) of the research. Depending on the planned research, there are minimum two, but sometimes three or more theoretical answers that can exist. A preliminary analysis of these hypotheses can provide considerable help for the future, when we already have the results of our investigation.

This practical differs from the others along the course, where the students join to the experimental work after the previously mentioned three steps of research planning. Our main goal here is to provide the students a chance to conduct a full research right from the first step. They have to discover an interesting phenomenon, form a suitable research question, plan the proper data collecting methodology, and execute the observation. In the next paragraphs we provide a brief theoretical background about how to describe animal behaviour scientifically, and what kind of basic ethological procedures are available for conducting an observational research.

2.2. 2.2 Components of behaviour

According to one of the main principles of ethology, behavior is a process that is dividable to discrete behavioural elements. These can be non-overlapping, for example a hen cannot sit and stand at the same time. Other behavioural elements can overlap, for example the hen can peck while it is standing. The fact that a continuous string of behaviour can be divided to elements had a very important part in forming modern ethological thinking. Natural sciences require exact measuring methods, and this in turn would be impossible without unambiguous definitions and repeatable experiments. Knowing a few basic definitions are also necessary for the successful participation on this practical.
