Some aspects of bill morphology in relation to ecology in the great tit Parus major

Gosler, Andrew January 1987 (has links)
The study concluded that bill size was highly adaptive in that it was related to fitness (in the broad sense) or to some correlate of fitness. The results are considered in terms of existing niche theory and especially of "character displacement" and the "variable niche hypothesis".

The singing behaviour of coal tits (Parus ater)

Adhikerana, Asep Sunjaya January 1992 (has links)
This thesis investigates the singing behaviour of coal tits (Parus ater) from two different study sites. A background to the functional significance of songs in a broad context is given in Chapter 1. This chapter also briefly introduces the biology of coal tits. Chapter 2 describes more general aspects of coal tit songs, and evaluates and compares the variability in song structure of two coal tit populations. The study has looked at the distribution of songs within populations, and at the effect of distance between individuals on the composition of their repertoires. The results are presented in Chapter 3. A new hypothesis has been proposed to explain the significance of song repertoires, namely the anti-exhaustion hypothesis. The hypothesis was tested on coal tits, and the results are presented in Chapter 4. Using playback experiments the singing interaction in coal tits was investigated. Two experiments were carried out in order to test the predictions that a bout of song could give information about individual's fitness, and that song length might indicate individual 'strength'. The results are presented in Chapter 5.

Efekt velikosti stimulu v diskriminačních a kategorizačních procesech u ptáků / Effect of stimulus size in discrimination and categorization processes in birds

NÁCAROVÁ, Jana January 2013 (has links)
The mechanism of predator categorization has not been understood well yet. I examined how coloration pattern and predator size influence categorization by a prey under laboratory conditions. I tested the reaction of great tit (Parus major) to the plush dummies of sparrowhawk (Accipiter nisus), coloured as sparrowhawk, pigeon, robin and great tit. The same color variations were made in the sizes of a sparrowhawk and great tit. My results indicate that the coloration plays the main role in the recognition. The size is not important in the dummies coloured as the predator and the conspecific but it plays a role in recognition of other tested dummies (coloured as the pigeon and robin).
