The Lower Tana River Forest patches in Coastal Kenya are remnants of a vast tropical forest that once extended from the East Coast of Africa to the Congo Basin during the Miocene (some 26 million years ago). The forest now occurs patchily on each side of the river. The forest fragments are among the key forests for bird conservation in Africa and qualify as an Important Bird Area (Bennun & Njoroge 1999). However, there has been little systematic ornithological work in the Lower Tana, and information on the avifauna is patchy and scant. The forest fragments are at different succession stages and are unlikely to be of equal conservation importance to birds hence the studies sought to characterize the avifauna of the different forest types in Lower Tana River and to identify the most important fragments for bird’s conservation. This dataset gives a baseline information on the ringing events of birds at the Lower Tana River forest fragments including; Mchelelo, Mnazini South, Mnazini North, Congolani Central, Nguru North, Nguru South, Makere West,Baomo South, Maroni East and Kipende West between 1999 to 2001. This dataset represents 279 records of birds ringed in the Lower Tana River forests between 1999 -2001. A total of 38 species were ringed.Purpose
Lower Tana River Forest is listed among the key forests for bird conservation in Africa and qualify as an Important Bird Area hence is of conservation significance. This dataset was provided to act as a reference point against which to compare current bird's situation in this forest. It will also give a focus for contemporary survey work and management decisions. Raising the profile of data for the conservation of four forested African landscapes project has played a role in unlocking this dataset which has been locked in unpublished reports for many years. Later, this project will create relevant and applicable tools to interpret this dataset hence guiding the conservation work and policy decisions of the Lower Tana River Forest Fragments.
Sampling Description
Study Extent
The bird ringing was done in the Tana River Primate National Reserve (1⁰55’5, 40⁰5’E) located along the lower reaches of the Tana River. This reserve covers 169km2 of which around 11km2 is riverine forest. 15 forest fragments of this including: Mchelelo(63ha), Mnazini South(50ha), Mnazini North(38ha), Congolani Central(50ha), Guru North(5ha), Guru South(46ha), Makere West48ha), Mchelelo East(10ha), Sifa East(150ha),Wenje East(525ha), Makere East(4ha), Baomo South(30ha), Maroni East(4ha), Maroni West(16ha) and Kipende West(14ha) were covered.Sampling
The understory birds were captured using mist nets set along paths in each site, ringed, biometrics taken then later on released.Quality Control
Species identification and ringing was done on site by a team of bird experts from the Ornithology Section, National Museums of Kenya.Method steps
- At each study site, a narrow trail, 105 m long, through the understory vegetation was cleared. Small mesh mist-nets 3M high and 105 M long in total length were erected using bamboo poles and operated for two mornings at each site. Nets were opened for four hours each morning starting from between 06:30-07:30 h depending on availability of security personnel.
