This work focuses on the behavior of birds approaching aircraft at the Murongo national airport in Bunia. To arrive at the results of this research, the Point Abundance Index (PIA) method was used. Field observations were carried out every Tuesday and Thursday from 6: 30 a.m. to 11 a.m. and from 4: 30 p.m. to 6 p.m. After these observations, 11 species of birds were identified (Leptoptilos crumenifer, Ciconia episcopus, Prinia somalica, Macronyx croceus, Corvus albus, Aquila rapax, Turdus pelios, Hirundo nigrita, Ploceus cucullatus, Lanius cristatus and Pycnonotus barbatus) and having manifested 10 behaviors, including: resting, feeding, social, territorial and aggression, before takeoff or landing versus moving, fleeing, nesting, leisure and habituation during landing or takeoff. Corvus albus and Aquila rapax offer high percentages of birds observed (respectively, 45.1% and 17.1%), i.e. 93 individuals (Corvus albus) against 36 (Aquila rapax) out of a total of 206 having demonstrated behavior towards the movement of aircraft. The Aquila rapax species has experienced collisions with aircraft 12 times than the other two (respectively Corvus albus and Hirundu nigrita: once). The behavior of these 3 species (Aquila rapax, Hirundu nigrita and Corvus albus) in the face of aircraft maneuvers during takeoff and/or landing of aircraft led to their death. This work contributes to understanding the behavior of avifauna when aircraft approach Bunia airport.

This work concerns the inventory of avifauna frequenting the Murongo airport in Bunia. The bird specimens were obtained by the Capture-Mark-Recapture (CMR) method using the mist net trapping technique. In total, 6 nets (3 m wide, 10 m long and 35 mm mesh size) were used and observations (3 times per week) with the naked eye completed the sampling. Fieldwork was done every Sunday; the nets were installed in a line. They remained in place for nine hours and the surveys were carried out every 2 hours between 8: 00 a.m. and 5: 00 p.m. This study led to a census of 35 species of birds. The concession of the Régie des Voies Aériennes (RVA: S1) presents a numerically high percentage, i.e. 89.02%. Specifically, the two sites (S1 and S2: around RVA) have the same number of species, respectively (50%) each. The species Psalidoprocne obscura has a high percentage (43.16%), followed by Corvus albus (20.14%). This work contributes to the knowledge of avian fauna that plays an important role in the functioning of different types of ecosystem (through dispersal, pollination of plants, destruction of insects and rodents harmful to other animals (including man) than for plants.

This work focuses on the avian biodiversity inventory of the city of Bunia. The bird specimens were obtained by the Capture-Marking-Recapture (CMR) method using the Japanese net trapping technique. A total of 5 nets (3 m wide, 8.5 m long and 35 mm mesh) were used and observations with the naked eye completed the sampling. Fieldwork was done every Sunday; the nets were installed online. They remained in place for eight hours and the readings were made every 2 hours between 08:00 and 16:00. This study leads to a census of 53 species of birds. Spatially, 29 species are constant and 24 accessories. The Shalom University concession (S2) has a high specific richness (45 species), followed by the Pan-African Higher Institute of Community Sciences (S4) and the Grand Seminary (S1) (22 species each). Temporarily, 30 species are constant and 23 accessories. The first rainy season offers a high specific percentage (34.5%), followed by the second rainy season (27.4%) and the first dry season has a low percentage (15%). The Shalom University concession has a high number of individuals caught and species recaptured. The same concession (S2) offers a high number of individuals (349 out of 756) observed. The first rainy season also offers a high number of individuals (349) observed, followed by the second rainy season (127 individuals).
