Seabird temporal composition, abundance and habitat use in Punta La Metalera (Arequipa, Southern Peru)

Islands, islets, and guano capes provide a unique variety of habitats for seabirds. Their variability determines the structure and dynamics of the community. Studies about the temporal diversity and habitat use of these systems in southern Peru are lacking. The aim of this study was to analyze the abundance, composition, and behavior of seabirds at Punta La Metalera (El Faro) in the province of Islay in the Arequipa region of southern Peru. We recorded a total of 12 species. One of these is endemic to the Peruvian coast (Cinclodes taczanowskii), one is considered in endangered (Spheniscus humboldti), and four have been assigned near threatened status (Phalacrocorax gaimardi, Pelecanus thagus, Sula variegata and Larosterna inca). Some of these birds belong to the guano bird group. Laridae was the most abundant family due to Larosterna inca, which showed the highest number of individuals. Temporal variation showed that species were most abundant in December and January. The habitat was mainly used for resting, preening, and feeding. However, nesting was also recorded for six species. Based on the little information previously available for this region our findings indicate that Punta La Metalera is an important area for the development and reproduction of some of the species recorded.

Patterns of morphological diversification in the Ramphastoidea reveal the dramatic divergence of toucans from a conserved morphotype

Morphological traits offer insights into an organism s ecological niche, species interactions, and patterns of community organisation. Pantropical lineages - animals and plants distributed across the three tropical continental regions of Asia, Africa, and America - provide a way to test how different environments and communities influence morphological diversification. Here, we examined a monophyletic group of frugivorous birds, the barbets and toucans (Ramphastoidea), which diversified independently on three continents, to investigate whether clades in each region exhibit similar (phylogenetically constrained) or distinct (ecologically influenced) patterns of morphological diversification. Our results show that despite differences in community dynamics in these regions, lineage accumulation patterns through time on all three continents are broadly similar, putatively due to phylogenetic niche conservatism. We quantified morphological variation in light of phylogenetic relatedness to further reveal that all barbet lineages across continents occupy a conserved region of morphospace after correcting for variation in size. However, in the Neotropics, one lineage, the toucans, have diverged dramatically from typical barbet space and converged toward (yet are distinct from) the trait space occupied by the distantly related hornbills in Asia and Africa. Additionally, we found no link between climatic variables and morphological traits. We conclude that barbets exhibit a conserved morphotype across continents and have diversified by scaling mainly in body size. However, the absence of other large frugivorous birds may have allowed toucans to diversify into a different region of morphospace of increased bill/wing to tail/wing ratios. By examining different continental lineages of a single monophyletic bird group, we shed light on the contrasting effects of regional ecological factors and phylogenetic constraints on morphological diversification.

An Analysis of Heterogeneity in German Speaking Birdwatchers Reveals Three Distinct Clusters and Gender Differences

The purpose of this study was to segment birdwatchers into clusters. Members from a wide range of bird related organizations, from highly specialized birders as well as Facebook bird group members were studied to provide a diverse dataset (n = 2766; 50.5% men). Birding specialization was measured with a battery of questionnaires. Birding specialization encompassed the three constructs of skill/competence, behavior, personal and behavioral commitment. Additionally, involvement, measured by centrality to lifestyle, attraction, social bonding, and identity, was used. The NbClust analyses showed that a three-cluster solution was the optimal solution. Then, k-means cluster analysis was applied on three groups: casual/novice, intermediate, and specialist/advanced birdwatchers. More men than women were in the specialist/advanced group and more women than men in the casual/novice group. As a conclusion, this study confirms a three-cluster solution for segmenting German birdwatchers based on a large and diverse sample and a broad conceptualization of the construct birding specialization. These data can be used to address different target audiences (novices, advanced birders) with different programs, e.g., in nature conservation.

The Effect of Garlic (Allium sativum) Extract Pesticides in Repelling Rice Eating Bird Pests

One of the main problems in rice cultivation is the difficulty of controlling bondol bird (Lonchura punctulata) pest attacks. Bird pest is one of the main enemies of farmers that can reduce crop production. Increasing bird populations cause crop yields to decline. So that one way that can be used in repelling bird pests is by giving pesticides from garlic extract. Allicin is a compound that gives garlic its distinctive smell which repels bird pests. This study aims to determine the effect of the provision of plant-based pesticides from garlic extract in repelling rice-eating bird pests. This research was conducted in Tonasa Village, Takalar District, South Sulawesi, Indonesia. Research implementation methods include the manufacture and testing of pesticides liquid extracts of garlic and application in the field by spraying, this spraying is carried out in the morning, afternoon, and evening before making the observations. Observation parameters use the method of comparing initial observations and final observations observed in the morning, afternoon and evening (comparison method) by conducting initial data collection (without using pesticides) and final data collection (after spraying pesticides), the average number of groups of birds that attack 1 Ha of rice fields. The results obtained on average indicate quite a lot of attacks in a day, especially in the morning. After the use of the automatic repellent method the attacks of bondol bird groups tend to decrease where in the morning ratio of 20 to 33 decreases to 5 to 13 attacks, while the ratio of daytime 8 to 15 decreases to 3 to 7 attacks and the ratio of the evening 19 to 33 decreases to 6 to 12 bird group attacks. So that the administration of garlic extract pesticides is effective in reducing bird pest attacks.

Systematic atlasing in Hessequa – Report on the first cycle of seasonal monitoring

Bird atlasing in the Hessequa region of the Western Cape has progressed beyond mapping to monitoring. During a three-year period within 2014/17, the U3A Stilbaai Bird Group upgraded the distribution maps using a strategy which aimed to even out coverage per grid cell, and achieve minimum mapping standards. In the two-year period December 2017 to November 2019, the group implemented a new strategy that would result in each of the 75 pentads in the Hessequa Atlas Area being atlased in each of the four seasons over a two-year period. Using a chessboard pattern to split the 75 pentads into two sets, the first set was atlased in summer and winter in the first year and autumn and spring of the second year. The second set was atlased in autumn and spring of the first year, and summer and winter of the second year. This paper reports the successful completion of the first monitoring cycle.

Diurnal raptors of West Africa woodland-farmland mosaics: Data from walking-transects in eastern Guinea-Bissau

Guinea-Bissau is a small country in West Africa, which in spite of its rich biodiversity and the high proportion of protected areas remains under-surveyed in relation to most animal groups, including raptors. The first scientific articles about raptors were only very recently issued. Here, we report raptor occurrence data from eastern Guinea-Bissau. Raptors were surveyed in the dry season along transects walked around 21 villages in a rural woodland-farmland mosaic landscape. The raptor assemblage is composed of 25 species of which the hooded vulture, the lizard buzzard and the African harrier-hawk were the species more often encountered, followed by the African white-backed vulture. The palm-nut vulture, black kite, brown snake-eagle, grasshopper buzzard, African hawk-eagle, grey kestrel and lanner falcon were secondary, although not uncommon species. The remaining species were seldom recorded. The study complements previous knowledge on this bird group, specifically in the central-eastern part of the country, and reaffirms the international relevance of Guinea-Bissau for the conservation of the hooded and African white-backed vultures.

Effect of the antioxidant “Bisphenol-5” on the digestibility of nutrients in the diet of broilers

The addition of the antioxidant “Bisphenol-5” in the dietary feed of broiler chickens in the amount of 0.0002, 0.0004, 0.0008 and 0.0015 % of its weight contributed to the dietary nutrients digestibility enhancement, their absorbability and assimilation of nitrogen, calcium, phosphorus, which affected the increase in the intensity of animal growth. The effective dose application of the antioxidant under study in broiler raising is 0.0008 % of feed weight. Feeding of mixed fodders enriched with antioxidant at the given dosage of the third experimental bird group increased the digestibility of organic matter by 4.28 % (p ≤ 0.001), increased absorption of nitrogen, calcium, phosphorus by 1.07, 0.27, 0.2 g (p ≤ 0.001) respectively and increased average daily live weight by 13.6 % (p ≤ 0.001) compared with individuals in the control group.
