  Pigeon breeding has a history dating back several centuries in Hungary. It has internationally renowned and accepted results. Our aim was to estimate the range of values related to Hungarian pigeon breeding and draw attention to the importance of their conservation. We studied the biological values of native breeds and the appearance of pigeon breeding within the Hungarian culture. These include the use of the symbol, the relating beliefs and customs, language, gastronomy, architecture and object values, as well as the community-building effect. Based on our results we can say that this topic is worthy of further research.

  In the course of our examination, we assessed biometric data that determine gender, we evaluated sexual activity, measured the nourishment and necropsies of two feral pigeon populations feeding and nesting at animal breeding farms. The changes in the body weight of the different genders were significant on both farms (p<0.05).
  The body weight and the crop volume of the birds were not significantly different at the examined farms.
  On both farms, the elemental food source of the birds was the fodder and corn kernels given to cattle, and was supplemented by that of the pigeons living at the Debrecen farm with food from surrounding farms and with other seeds (pea, millet, rye).
  By the examination of the genitals, the birds collected from the Nyírbátor farm showed sexual activity from the beginning of spring, and in the summertime decreasing activity is characteristic, while the pigeons from the Debrecen farm are only active from the summer months. In the course of the examinations in the Veterinary Institute of Debrecen, the birds proved to be free of parasites and the results of the Newcastle disease analysis were negative as well. The bacteriologic analyses showed a different proportion of E.coli, Pasteurella multicoda, haemolysing Staphylococcus bacteria at the two cattle farms. During the examinations for the statement of Salmonellas, this causative agent was stated only in case of birds that spend nights and nested in the town, which allude to human origin. We demonstrated Eimeria oocysts during the parasitological examination of the fecal samples in 5 cases at the Debrecen, and in 1 case at the Nyírbátor farm.

  The aim of this study was to determine morphological characteristics of the tumbler pigeon breed of Satu Mare. This pigeon breed was first described in 1932 and was very close to extinction at the end of the 20th century. Data collection was carried out in two stocks having birds from three breeders (Bertalan Juhos, Cosmin Lupu and Werner Hartmann) in Satu Mare. In addition to the breeder, sex and color variety were also evaluated. The performed conformation measurements were statistically compared using multifactor analysis of variance. Lupu’s birds were longer compared to other breeder’s stock, while beak and wing was longer in Juhos’s stock. Thoracic perimeter was smaller whereas queue length was the longer for Juhos’s birds. Cocks’ values were significantly exceeding values of hens, except beak length. Recessive red pigeons had longer body than blue birds. Beak length of recessive yellow pigeons was significantly longer that it was computed for black birds. Wingspan was longer for dun birds than it was estimated for recessive yellow pigeons. These differences show that there is reasonable genetic variability in the breed which is desired in small populations. Due to the variability within the breed, stabilising selection might be favorable, with a special account for avoiding inbreeding.

  Chromatometric examination of the plumage of birds is a poorly researched topic. We have approached this issue in primarily aspect of differences in plumage of species. Moulted feathers sample collection method has been increasingly used. Reliable identification of feathers becomes an increasingly important issue, hence need for an exact measurement-based methodology. Eurasian Collared Dove (Streptopelia decaocto) and Feral Pigeon (Columba livia domestica) primary, secondary and tail feathers were studied. Chromatometric parameters of feathers were measured in CIELAB color system and then statistical analysis (Independent samples t-test, Descriptive Statistics, Discriminant Analysis) was performed to compare the two species. Instrumental measurements has been confirmed the high similarity between colors of the two species, however species specific differences were also found. Lightless (L*) value were significantly characteristic of particular species, while the red/green (a*) and yellow/blue (b*) value had lower Predictive Power. We identified feathers and the variables which useable to separate the two species and determined the associated Confidence Intervals of these values. Our results may draw attention to a new potential direction for exact identification of the moulted feathers during sample collection.
