Birds play a vital role in many ecosystems, acting as both predators and preys for other living organisms. Therefore its important to monitor the population of various bird species in the environment in order to maintain balance in the ecosystem. This process will become tedious if it is done manually as it involves handling large sets of data at the same instant. We can do this by developing an automatic bird species recognizer which identifies the bird species based on bird songs and voice signals. In this research, we have used a tenth-order LMS adaptive filter to remove noise from bird voice signals which are recorded in different environmental conditions where different noise frequencies are present. The design of a tenth-order LMS adaptive filter using MATLAB has been implemented. The performance and characteristics of the filter for five different methods of LMS has been shown. After removal of noise from the noisy bird voice signal using LMS algorithm, we have made use of cross correlation to identify the bird species that it corresponds to. Signal to Noise Ratio (SNR) and Mean Square Error (MSE) of the filtered bird signals obtained using the variants of LMS like Normalized LMS, Sign-Data LMS, SignError LMS and Sign-Sign LMS have been estimated and compared. We have made use of signal processing tool kits and various noise parameter schemes have been computed to show the effectiveness of the designed filter in the field of bird recognition.

Abstract Studies of local Tree Sparrow Passer montanus populations from urban parks of Polish cities reveal changes in abundance and in nest site selection which differ from data collected from farmland. These changes are not always synchronous among neighbouring cities and parks. Several urban declines are difficult to explain, chiefly when obscured by the changes in the number of artificial nesting sites. One such case was a recorded decline Tree Sparrow and a switch to nesting in buildings observed in the Szczytnicki Park of Wrocław, after colonization by pine martens Martes martes. Judging from this the absence/presence of important predators or nest predators in other urban parks of Polish cities may be an additional factor promoting Tree Sparrow declines. It is suggested that a lack of precise data on the intensity of (mosaic-like in time and space) predation pressure in agricultural and urban landscapes should be considered when explaining the reasons for population changes in other bird species.

Offspring Investment

Background One possibility suggested regarding female post-mating strategies is differential allocation into offspring investment. Female birds produce not only the largest, but also most colourful eggs of all oviparous taxa. Larger eggs provide space for bigger embryos, or more nutrition for their development, but the question why eggs are more colourful and why there is variation in eggshell colouration remains. In this context, the focus of interest has been to explain inter-clutch variation but in many bird species, eggshell colouration also varies within a clutch. Surprisingly, less attention has been paid to this phenomenon. Therefore, we propose the “female egg recognition” hypothesis, suggesting that mothers use colour characteristics to interpret egg attributes and allocate further investment into each egg accordingly. To evaluate the feasibility of the hypothesis, we tested several underlying predictions and examined their suitability using a dataset from our tree sparrow (Passer montanus) study. We predict (i) substantial within-clutch variation in eggshell colouration which, (ii) should be related to laying sequence, (iii) reflect egg quality and, (iv) should stimulate a female response. Methods Eggshell coloration data were obtained via digital photography under standardized conditions, taken after clutch completion. Lightness (L*), representing the achromatic properties of an egg has been chosen as the most important predictor in dark cavities and was related to egg quality and position in the nest. Results In our tree sparrows, first and mainly last eggs were less pigmented, providing information about laying order. Egg volume, which predicts chick quality, positively correlates with eggshell coloration. Finally, we could show that female tree sparrows placed darker, but not bigger, eggs into more central incubation positions. Discussion All basic prerequisites for the “female egg recognition” hypothesis are fulfilled. In this context practicability and feasibility of the hypothesis and alternative explanations are discussed. However future work is necessary to determine a direct effect on offspring condition.

Abstract The Scaly-breasted Munia (Lonchura punctulata) is known as a common pest in the Indonesian rice field. However, there is no study on the daily activity of this species. This study aims to determine the daily activity of L. punctulata in rice field habitat. The research was conducted on April-May 2021 in Aceh Besar (Sumatera), Wonogiri (Central Java) and Tulungagung (East Java). Sixty-three hours of observations were carried out in seven days using scan sampling and data recorded using the continuous method. Observation time was divided into morning, afternoon, and evening for three hours each time. Data variation was analyzed with ANOVA and Kruskal Wallis, then the correlation between behavior and temperature was analyzed using Pearson and Spearman Correlation Test. Our results show that moving (35.9 – 65.2%) and feeding (16.9–44.69%) are the most frequently observed behaviors. Only sunbathing behavior in the afternoon was significantly different in three locations (p-value < 0.001). Correlation analysis shows that feeding and sunbathing behavior have an inverse correlation with temperature. However, resting behaviors increases with increasing temperature. Temperature affects daily activities due to the bird’s thermoregulatory system. The other factors also influence L. punctulata behavior, such as other bird species presence and bird scaring activities.

A total of 77 species from 34 families was recorded from 11,863 observations from November 2012 to April 2013 (six months) within Universiti Malaysia Sarawak (UNIMAS) campus using line transect method. This bird list is dominated by Asian Glossy Starling (Aplonis panayensis) with 4,917 observations (41.45%) followed by Eurasian Tree Sparrow (Passer montanus) with 867 observations (7.31%) and Yellow-vented Bulbul (Pycnonotus goiavier) with 752 observations (6.34%). This study reports higher diversity (H’ = 2.5) compared to previous studies. Density of bird was estimated at 6.24 individuals/ha. In order to explore the interspecific interactions between species, 19 bird species with (1,189 observations) most observations were subjected to bipartite network analysis. Based on the network analysis it appears that birds partition food resources spatially and by food type. The highest niche overlap occurs between foraging technique (0.61) while lower overlap was observed for height (0.44), types of food (0.42) and foraging substrate (0.42). This suggests that birds were exploiting similar resources but segregated spatially. Therefore birds are partitioning their niche to allow coexistence and to adapt to human modified landscape. This study has provided valuable information in characterising the assemblage and understanding the distribution of the birds in a campus landscape.

Birds are important indicators to determine the quality of habitat. They played an important role in maintaining the balance of our ecosystem. This study aims to determine the species of birds and its diversity within the Central Mindanao University main campus. A line transect method combined with bird watching technique were used within the two month avian survey. A  total  of  27 species belonging to 21  families were  recorded namely, Accipitridae, Alcedinidae, Apodidae, Ardeidae, Artamidae, Bucesotidae, Campephagidae, Columbidae, Corvidae, Dicaeidae, Estrildidae, Hirundiniidae, Laniidae, Meropidae, Nectariniidae, Phasianidae, Pycnonotidae, Sturnidae and Sylviidae. Out of the 27 bird species observed, 18 resident, 3 resident-migrant, 5 Philippine endemic and 1 island endemic. The most observed species are Euarasian Tree Sparrow (Passer montanus) and followed by an introduced species which was Feral Pigeon (Columba livia). Most of the species observed were commonly found in urban communities, agroecosystem and along the forest edge. Some species of birds belonging to family Nictariniidae and Dicaeidae are associated in areas with flowering trees and there are seldom observed in other points. The average diversity of all points H’= 0.94 which is quiet low and it requires more sampling effort and other technique to record silent or shy species.

Summary Reintroductions aim to re-establish a viable population within the indigenous range of living organisms, especially of threatened species. The population of the Asian Crested Ibis Nipponia nippon, a well-known ‘Endangered’ bird species, has increased over 100 times since wild populations were rediscovered in 1981, and several reintroduction projects were subsequently carried out in its former range. An experimental release of the Asian Crested Ibis was conducted in Qianhu National Wetland Park located in the southern part of the Loess Plateau, China. It is vitally important to monitor released birds (at least their survival and breeding), to inform subsequent releases in other suitable sites. During extensive post-release monitoring, data on capture-recapture and reproductive status were obtained using banding, radiotelemetry, and field observations. Using the Cormack-Jolly-Seber (C-J-S) model, the average annual survival rates were estimated to be 0.569 (95% CI: 0.353–0.762) for released individuals and 0.643 (95% CI: 0.038–0.987) for all individuals. From 2014 to 2018, a total of 14 breeding pairs produced 28 eggs and 10 fledglings with successful reproduction of the second generation. The mean clutch size was 2.07 ± 0.25 (n = 29), and the breeding success was 34.5%. Predation and poor habitat quality have been shown to be the main factors affecting the reintroduced population at establishment stage. Some management suggestions at the metapopulation and ecosystem levels, including further release, predator control and habitat improvement, have been proposed.
