Pełny tekst źródłaThe fast decline of wild life on the planet has led innumerable researchers to discuss different conservation strategies by both maintaining animals in their own natural habitat and reproducing in captivity. Reproduction in captivity becomes difficult when these animals do not present sexual dimorphism (absent in many species, specially in psittacines), requiring the use of methods for sex identification to form couples. Thus the use of magnetic resonance imaging (MRI) to identify the sex of birds without sexual dimorphism through the visualization of their reproductive organs has been studied. Ten animals of the Aratinga leucophthalmus species were anaesthetized and subject to tomographic exams. In the tomographic images obtained it was possible to visualize the testicles identifying the male sex in sexually mature birds. However, in the females, the left ovary (possible immaturity) could not be precisely characterized by this method, due to its anatomical shape. To confirm the results of the tomographic exams, analyses of DNA polimorphism were performed.

Pełny tekst źródłaAllergic diseases represent one of the most important public health concerns. Among them, Bird Fancier’s Lung disease (BFL) is a respiratory illness associated with repeated inhalation of antigenic proteins, present in bird droppings, feathers and blooms. Currently, little is known about the nature of the antigens involved in the disease. The detection of immunoglobulin G (IgG) specific etiologic agents is an important factor in diagnostic and therapeutic management.The objective of this thesis is to identify the antigenic proteins of pigeons and to produce them by genetic engineering in order to develop an effective and standardized ELISA-type serological test. The immuno-proteomic approach created combines the use of serological analyses (western blot, ELISA) and the identification by mass spectrometry of antigenic proteins and total proteins (shotgun) of pigeon droppings, blooms and serum. Thus, 14 antigenic proteins mainly located in droppings and blooms were identified, and 2 recombinant proteins were produced and then tested with ELISA.The recombinant proteins Immunoglobulin-lambda-like polypeptide-1 and Proproteinase E are highly effective for the serological diagnosis of BFL,with specificity and sensitivity rates of 100% and 84%, respectively. Orthologous proteins potentially involved in cross-antigen reactions were identified from budgerigar and hen droppings. This work made it possible to identify the antigenic proteins of pigeon droppings, to provide further details on their location, and to develop standardized and efficient recombinant antigens to improve the serological diagnosis of BFL.Additional studies on animals and cell models will be needed to explore the role of these proteins in the induction of the disease

In this report we discuss the importance of inexpensive electronic fieldguides which at the same time provide suitable user interface for maximum information transfer. The implications of software architecture are discussed during the course of designing the software model of a bird identifier fieldguide. This model is used to evaluate the behavioral performance and effectiveness of the user interface; both of which play a vital role in establishing the cost of the device. These observations are brought together in conclusion, where the potential role of electronic fieldguides in the domain of education and science are highlighted.

Pełny tekst źródłaA selection of southern African bird species were modelled in terms of the probability of these species colliding with or being electrocuted on overhead power lines in South Africa, based on morphological and behavioral factors. Species were included in the model on the basis of internationally recognized vulnerability to these interactions at the family level. The collision model performed poorly when tested against the actual reported mortalities for species contained in the Eskom-EWT Strategic Partnership Central Incident Register CIR)(chi-square of goodness of fit) at the individual species, family and within family levels. The electrocution model performed slightly better at the family, and within family level. Both collision and electrocution models performed better for the physically larger species (and families) and for those species with higher modelled probability of collision or electrocution. As the product of random carcass detection and reporting, the CIR data are biased in various ways. Testing the models against the CIR is therefore equally important for highlighting inadequacies in the CIR, as in the model. A number of new species have emerged as being of high collision (including most importantly African Pygmy Goose, Southern Ground Hornbill, Black-bellied Bustard, Yellow-throated Sandgrouse, Caspian Tern, Hooded Vulture, Bateleur, African Marsh Harrier, Black Harrier, Pink-backed Pelican and Yellow-billed Stork) or electrocution (Southern Bald Ibis) probability in theoretical terms, and will require further investigation to determine their actual probability of interaction. By mapping the combined distributions of those species with high probabilities of collision and/or electrocution mortality, a number of priority high risk geographic areas emerge around the country.

Abstract With the developments of aviation technology, bird strikes become a serious problem to human life and economy of the industry. In order to minimize the risk of bird strikes, it is necessary to develop habitat management practices for the bird species at risk. Therefore, it is critical to identify the birds caused the aircraft damage in order to take the proper damage prevention strategies. Feather microstructure technique is a forensic candidate method to apply for bird species identification for a bird strike issue. However, there are few researches using quantification of characters and multivariate analysis. The purpose of this study is to quantify the characteristics of downy region of contour feathers, and use discriminant analysis and morphological comparison with microscopy techniques to identify six air-foraging insectivorous birds at CCK Air Force base at Taichung in central Taiwan. The subpennaceous region structure was found in Apus pacificus only. Furthermore, 11 morphological data of Dicrurus macrocercus, Hirundo rustica, H. tahitica, H. striolata and Riparia paludicala were used in discriminant analysis and a 74.5% efficacy rate was found. The successful identification rates of the discriminant analysis by using barb length, barbule length, basal cell length, node number at proximal and distal barbule and pigmented node number at median and distal barbule provided were97.5%, 85% and 81.7% for D. macrocercus , H. tahitica and R. paludicala specimens correspondingly. The classification of H. rustica and H. striolata was not significant. However, the scanning electron microscopy (SEM) technique was able to distinguish the two species by comparing the distinct morphology of nodes for the two species. This study has established a systematic approach for the identification of bird strike remains and provided methods to build a microstructure feather data base for the forensic purpose of bird strike researches.

There are more than nine thousand and seven hundred bird species in the world. Interestingly, one-twentieth of worldwide bird species can be found in this small island we live. Despite abundant with various birds, most people in Taiwan cannot recognize what the bird is by its sound; even the bird is commonly seen. In this study, we attempt to develop automated techniques for identifying bird species based on their sounds. It is hoped that the techniques can help people learn such lovely animals by simply recording the bird sounds they hear. To begin, we apply the most prevalent speaker-identification method to the problem of bird sound identification. Several audio features, such as Mel-scale frequency cepstral coefficients (MFCCs), Renyi entropy, spectrum centroid, and Mel Spectral Centroid Cepstral Coefficients (MSCCCs), together with Gaussian mixture modeling are investigated. However, our experiments found that the resulting identification accuracy is far from satisfactory, and different audio features perform rather diverse. To improve the identification performance, we propose a two-stage paradigm based on a characteristic that bird sound can be divided into three classes, namely, bird call, bird call sequence, and bird song. It is found that MFCCs are suitable for bird song identification, whereas MSCCCs are suitable for bird call sequence identification. We therefore build two identifiers for bird call sequence and bird song using different audio features separately, and recognize which of the three classes an unknown test sound belongs to. Our experimental data comprises ten bird species, stemming from both commercial CDs and public websites. It is found that the identification accuracy can be largely improved from 60.37% to 80% using the proposed two-stage system.

Automatic bird sound identification system has been developed for several years. Traditional recognition approaches are modified from human speech processing systems. Features extraction algorithms usually used in the bird call identification are based on the human auditory models such as Mel-frequency cepstral coefficient (MFCC). However, the auditory model is not quite suitable for bird sound recognition owing to the different mechanism between human being and computer system. In this thesis, our bird call identification system is composed of three major parts: Time-frequency methods selection, reference templates training and bird sounds comparison. We analyze the bird call by transforming data into the time-frequency domain, which is used as the visual patterns for further feature extraction. In this study, a variety of transformations such as linear time-frequency transform, bilinear time-frequency transform and Hilbert-Huang transform are included in this recognition system. We have also made several comparisons between the normal time-frequency transform and the human perception related transform, and then conclude the best transform for different bird species.

To help people learn bird species from their sounds, this study proposes an automatic system that identifies bird sounds in a long audio recording. For each instant of a long audio recording, we perform timbre-based and pitch-based analyses. In the timbre-based analyses, Mel-frequency cepstrum coefficients are extracted from every short segment, and then tested by a Gaussian Mixture Model Classifier. In the pitch-based analysis, we convert sound signals from their waveform representations into a sequence of MIDI notes. Then, Bigram models are used to analyze the dynamic change information of the notes. The database used in this thesis consists of 2815 sound recordings from 20 bird species. We further concatenated all the recordings into an 885-sec long audio stream. Our experiments show that the identification accuracies obtained with pitch-based analysis, timbre-based analysis, and combined pitch and timbre-based analysis are 50.2%, 82.45% ,85.28%, respectively.

Pełny tekst źródłaPigeon droppings, found in abundance in most cities and towns where pigeons are found, are a source of potential yeast and molds into the environment. Invasive fungal infections are a cause of morbidity and often mortality in immunocompromised individuals. The objective of this study was to the identification of bacterial and mold agents from pigeon droppings. Pigeon droppings samples were collected from three locations during the winter and summer months and studied for the occurrence of bacteria, yeast and molds by utilising culture-independent techniques. Amplification of the 16S rDNA gene and the internal transcribed spacer (ITS) region, cloning and ARDRA and DGGE were used for the characterisation of the microbial populations followed by sequencing. Several mold and yeasts, as well as bacteria were found to be present in pigeon droppings, which can spread into the environment and be transmitted to immunocompromised individuals and children. DGGE analysis of the bacterial communities revealed banding patterns that clustered all but one winter samples and all summer samples, showing a high similarity among the microbial members in both seasons and sample locations. Fungal DGGE analysis revealed clusters that grouped summer and winter samples from Johannesburg and Pretoria while VUT samples were clustered on their own. From the identification of fungal and bacterial DNA, Cryptococcus species was the majority of fungi isolated from the dropping samples. Geotrichum, Kazachstania and Fusarium species were isolated from phylotypes obtained from ITS amplicons analysed by ARDRA. Lactobacillus and Enteroccoccus species, organisms usually found in the gastrointestinal tract were the common bacterial members identified. The results showed no difference in microbial communities across all sample locations, while seasonal changes also had no impact in microbial community patterns.
