“…Many frugivorous birds are able to use human-modified environments (such as crop fields and forest edges) and/or move across open areas and forest fragments (Gomes et al, 2008), thus increasing seed dispersal along their route and acting as "mobile links" (Lundberg and Moberg, 2003;Piña-Rodrigues et al, 2009). In this scenario, ecological restoration of degraded land also has the function of making this area more permeable and "bird-friendly", reestablishing links among isolated forest remnants and allowing gene flow and increasing biological and functional diversity (Cavallero et al, 2012).…”

Ecological restoration aims to retrieve not only the structure but also the functionality of ecosystems. Frugivorous birds may play an important role in this process due to their efficiency in seed dispersal. Color perception in these animals is highly developed, and then the colors of fleshy fruits may provide important clues for choosing plant species for restoration plans. This study aims to integrate bird color preferences and restoration of degraded areas, with an objective to evaluate the potential attractiveness to birds by colored fruits. We carried out an experiment with 384 artificial fruits made of edible modeling clay with the following colors: black, blue, green and red, with 96 fruits of each color in six sites, including four restored areas and two second-growth forest fragments. We also tested the possible effect of light intensity on fruit consumption by color. A total of 120 (38.6%) were assumed to be consumed by birds, and the fruit consumption varied in response to the location and light incidence. Consumption of black and blue fruits was not related to site by chance. Notwithstanding, red and black fruits were consumed significantly more than any other colors, emphasizing bird preference to these colors, regardless of location. Enrichment with shade tolerant shrubs or forest species with black or red fruits may be an alternative way to manage established restorations. In recently established or new restorations, one may introduce pioneer shrubs or short-lived forest species which have blue fruits, but also those having black or red ones.Keywords: artificial fruits, Atlantic Forest, frugivory, ecological succession, color perception. Preferência de cor de frutos por aves e aplicações à restauração ecológica ResumoA restauração ecológica tem a finalidade de recuperar não apenas a estrutura, mas também a funcionalidade dos ecossistemas, e as aves frugívoras podem desempenhar um papel importante neste processo devido à sua eficiência na dispersão de sementes. Como a percepção da cor nestes animais é altamente desenvolvida, a cor dos frutos carnosos pode ser uma característica importante na escolha de espécies de plantas para os reflorestamentos. Este estudo tem como foco integrar a preferência de cor de frutos por aves e a recuperação de áreas degradadas, objetivando determinar a atratividade potencial de aves por frutos de cores diferentes. Foi realizado um experimento com 384 frutos artificiais feitos com massa de modelar comestível nas cores preta, azul, verde e vermelha, com um total de 96 frutos em cada cor em seis locais, incluindo quatro áreas restauradas e dois fragmentos de floresta secundária. Também foi testado o possível efeito da intensidade de luz sobre o consumo de frutos conforme as cores. Um total de 120 (38,6%) frutos foi considerado consumido pelas aves, e o consumo variou em resposta aos locais e incidência de luz. O consumo de frutos pretos e azuis foi significativamente relacionado com o local. Os frutos vermelhos e pretos foram significativamente mais consumidos do...

“…Vicente et al 2010). The absence of frugivorous species was probably caused by the defaunation brought about by site degradation (Gomes et al 2008). Regenerating environments also furnish few food and reproductive resources for specialized frugivores, including cavities for nests and availability of fruits during the whole year (Sekercioglu 2006, Pizo 2007, Pillat et al 2010.…”

Annual changes in a bird assembly on artificial perches: Implications for ecological restoration in a subtropical agroecosystem. Biota Neotropica. 16(1): e0069. http://dx.doi.org/10.1590/1676-0611- BN-2015-0069 Abstract: Artificial perches are used in tropical forest restoration projects to increase the dispersal of seeds into restored areas. The ability of perches to enhance seed deposition depends on their ability to attract seed dispersing birds, as well as the correlation between the season of bird visits to perches and the phenology of fruit production in adjacent forests. Using data collected from a large-scale restoration project, we characterized the community of birds that utilize artificial perches over the course of one year. We hypothesized that the structure of a bird assemblage that uses artificial perches is affected by seasonal variation. We aimed to describe the richness, abundance and diversity of a bird assemblage on artificial perches in a subtropical Atlantic forest restoration experiment in Southern Brazil. Richness and abundance estimates of the avian fauna were obtained from eight artificial perches placed in four experimental plots (B2 y-old). Parameters of richness and abundance were compared using ANOVA. The bird assemblage was described using SHE analysis [richness (S), diversity (H') and evenness (E)], with additional estimates of occurrence and dominance. In total, 451 records of 32 ± 3.16 SD species were obtained. Thraupidae was the most numerous family (nine species, 28.12% of the total). Richness and abundance varied seasonally and were highest during spring and summer. Five migratory species of flycatchers were recorded between spring and early autumn. Perches were ineffective in attracting specialized frugivorous birds, emphasizing that seed dispersal tends to be carried out primarily by generalist omnivores in the initial phase of forest regeneration.

“…Selanjutnya, pada areal yang mengalami lebih banyak perubahan habitat seperti pada kebun, maka spesies burung yang memiliki nilai penting tertinggi adalah burung yang berukuran lebih kecil lagi, seperti burung bondol (Lonchura sp). Kondisi yang dijumpai di karst TN Babul tersebut sesuai dengan pernyataan Gomes et al (2008) yang menyebutkan bahwa pada areal yang mengalami perubahan habitat, akan terjadi penurunan jumlah spesies burung berukuran besar.…”

Burung merupakan bioindikator perubahan habitat. Penelitian ini bertujuan untuk mengetahui respons burung yang berhabitat di karst Maros-Pangkep, Taman Nasional Bantimurung Bulusaraung terhadap perubahan habitat. Penelitian dilakukan di tiga lokasi, dengan perbedaan tingkat gangguan, yaitu zona inti (minim gangguan), zona rimba (tingkat gangguan sedang), kebun masyarakat (tingkat gangguan tinggi). Pengumpulan data vegetasi habitat burung dilakukan menggunakan modifikasi metode garis berpetak. Pengumpulan data burung dilakukan menggunakan metode point count. Analisis data vegetasi habitat burung dilakukan menggunakan kerapatan vegetasi. Perbedaan komposisi vegetasi habitat burung dianalisis menggunakan indeks kesamaan komunitas Sorensen. Analisis data burung dilakukan menggunakan kepadatan populasi, indeks keragaman jenis Shannon-Weinner, indeks dominansi Simpson, indeks kemerataan jenis Pielou, serta indeks kekayaan jenis Margalef. Beda nyata pada populasi burung diuji menggunakan uji ANOVA satu arah, serta uji Tukey dan Bonferroni. Hasil penelitian memperlihatkan bahwa burung yang hidup di karst tergolong peka akan perubahan habitat, yang terlihat dari adanya perbedaan nyata pada populasi. Degradasi habitat berdampak pada berbagai tingkatan trofik, dan direspons burung dalam bentuk berkurangnya jumlah individu dan spesies, peralihan spesies burung yang memiliki indeks nilai penting (INP) tertinggi dari spesies dengan tingkat toleransi rendah ke tingkat toleransi tinggi, peralihan feeding guild burung yang memiliki INP tinggi dari frugivora ke frugivora-insektivora dan selanjutnya ke granivora, berkurangnya jumlah spesies berukuran tubuh besar, serta berkurangnya jumlah spesies yang membutuhkan tempat khusus untuk bersarang. Mengingat karst Maros-Pangkep memiliki berbagai peran penting, maupun nilai ilmiah dan keragaman hayati yang tinggi, maka diperlukan pelibatan berbagai pihak, untuk menjaga kelestariannya, termasuk penetapan seluruh areal karst Maros-Pangkep menjadi kawasan bentang-alam karst.
