Building youths’ capacity in bird research and scientific writing
Biodiversity conservation is facing many challenges. Science-based evidence and information are needed to address these challenges and to prioritize resources and time. Committed and skilled people are also key to successful biodiversity conservation.
The Bird Ringing and Monitoring Program (BiMO), a locally crafted program for Nature Tanzania members, was launched in September 2020 at Amani Nature Forest Reserve (ANR) with only 9 participants; 6 males and 3 females. ANR is among the 80 Important Bird and Biodiversity Areas (IBA) in Tanzania with many special (rare, threatened and near-endemic) birds such as Long-billed Forest-Warbler, Amani Sunbird, Southern (Usambara) Hyliota, and Usambara Eagle-owl. The first cohort targeted young members in their early career and especially those with passion with nature. The program aims at imparting practical knowledge and skills to Nature Tanzania members on birds and their ecosystem services. Participants were trained on the bird trapping techniques with a focus on the use of mist nets for understory bird species, bird handling and ringing. Most of the participants had not had a chance to handle birds previously and few had seen or heard about mist netting. It was an excitement for many of the participants.
All participants were guided to set mist nets, remove trapped birds, process them (measure weight, length of the tail, tarsus, beak, wings). Using 19 mist nets erected in four different forest patches of different sizes, 112 birds from 20 species were trapped, banded with aluminum rings obtained from the East African ringing scheme in Nairobi, Kenya and released. Some interesting species were African Broadbill, Sharpe’s Akalat, White-chested Alethe, Lemon Dove and Red-tailed Anti-Thrush. The four different forest patches had different levels of disturbances, and the presence of Maesopsis eminii, an invasive tree species at Amani was used to infer the index of disturbances in the respective forest patches. To obtain the disturbance index participants collected and measured the weight of the leaves of M. eminii against the total leaf litter weight from 30x30cm plots. We also measured other environmental variables to explain the disturbance index of the forest patches. We used birds to demonstrate the effect of habitat disturbance and fragmentation on biodiversity. The results from the brief study, of two consecutive days, were amazing and meaningful results to demonstrate the intended objectives as shown in the below graphs.

The influence of flower colour in flower visitation by potential pollinators.
The other component covered during this training focused on avian ecological services, and in this part, the focus was on avian pollination ecology. Although targeting avian pollinators ‘ornithophily’ particularly sunbirds, other flower visitors (butterfly, bees, wasps etc.) were investigated. Participants conducted field observations to study the ‘pollination syndrome’ and explain the role of colour, morphology and odor in determining types of pollinators. Participants investigated the flower visitors in farmland mosaic at Amani and took measurements/ estimates of the corolla tube length (CTL) and sunbirds’ beak length to be able to identify the effect of morphology on the sunbird flower visitations and behaviour. While doing this exercise, the nectar robbing behaviour was observed for some sunbird species on certain flower types, for instance, Olive Sunbird was observed robbing from morning glory flower (CTL=5.7cm). This scenario happens especially when a pollinator is feeding on the flower with longer corolla tube than its beak length.
The point count method was explained to participants and used to collect information on the abundance of avian pollinators in the same general areas where flower visitors were investigated. Participants had also time to conduct focused birdwatching for rare and special birds at Amani that were not trapped in the mist nets. They include Long-billed Forest-Warbler, Southern Hyliota, Half-collared Kingfisher and Giant Kingfishers. There were also sessions for night walks for species that are easily seen during night.
The ten-days training (23rd Sept to 2nd Oct 2020) started with general introduction of BiMO and the area (done in the ANR conference room), where Mr. Emmanuel Mgimwa (NT CEO) gave a brief presentation on BiMO, its evolution, aims, objectives, and envisioned outputs. Introductory presentations were followed by a talk from Dr. Jasson John from the University of Dar es Salaam (UDSM) who explained the importance of ANR and the Eastern Arc Mountains (EAM) in general for the conservation of birds in Tanzania. The same ANR venue was used on the last day where participants made group presentations of the information obtained during the field training. This session was preceded by the guidance on data management, analyses, presentation and scientific report writing. The ANR Conservator and his team extended a warm welcome to BiMO participants and the Conservator gave a presentation about Amani before the group presentations.
In summary, the following topics were covered during the training period and participants were awarded a certificate of attendance at the end of the program;
- Avian pollination ecology.
- Bird survey techniques: point count, mist netting and bird ringing.
- Introduction to Scientific Writing and Publications
The BiMO initiative is a partnership program between NT and the Department of Zoology and Wildlife Conservation, UDSM, in which the first cohort drew participants from the UDSM, College of African Wildlife Management – MWEKA, Attraction Bird Club (ABC) – Arusha, National College of Tourism and few non-aligned Nature Tanzania members. In addition, 7 students from the University of Dodoma on their field attachments at ANR joined some of the sessions during BiMO. In the future, the program aims at inviting participants from all higher learning institutions in the country, with the hope that it will grow to include participants from other countries.
This being a membership activity, all BiMO participants must be a member of NT. Nature Tanzania members, partners and friends made this first footing of BiMO a success. In particular we thank NABU (BirdLife in Germany), BirdLife International and its partners for the support extended to NT and BiMO. Stay tuned for the BiMO next call by updating your membership status. To join NT membership kindly contact NT via firstname.lastname@example.org
