Species Frequency Richness
Method What do we do in SFRM?
Trail Transect (walking, observing and
enumerating)
Choice to use (foot paths, motorable roads,
navigate to reach a random point using GPS)
Cover and Cross various habitat types and
eco-types.

Surveyors Skills
Identification Skill Direct sighting of a species
Morphological distinctness
Vigilance at Movements Flight and display behavior
Foraging Bathing in water and soil
Bio-acoustical Skill Vocalizations (seasonal call, matting, territorial call, and alarm call)
Detective Skill Signs of evidences (feathers, dead remains, egg shells, nests &
droppings) Other Skills
Clues such as carrying nest and food materials

Surveyors Skills contd..
Mechanical Skill
Distractive approach
phishing : attract birds as phishing frequency
somehow lies within the call/sound frequency of
some birds/small birds or phishing is perceived as
threat/enemy.
Mimicry calls: of predatory species hooting
mimic ofGlaucidium brodiei(Collared Owlet). Call Playback: pre-recorded playback or at site
record song and playback.

Surveyors Skills contd
Be Aware
Of species of National Concern (FNCA, 1995)
Of species of International Concern (IUCN,CITES)
Of species Highly Exploited for food, medicine
and trade
Of Habitats or Eco-types

SYSTEMATIC DATA COLLECTION
1. First 20 bird species is recorded (List 1).Record effort made (time) to complete List 1.
2. List 2 is started and a further 20 species isrecorded. Each list must contain 20 firstspecies, but subsequent lists can includespecies previously listed. However, effortsmust be made to exclude the sameindividual/flock bird from the list.
3. Then List 3 is started4. List is repeated until no new species is
recorded

SYSTEMATIC DATA COLLECTION
contd..
5. A running species total/bird species diversity is
obtained by extracting the number of species in
List 2 that were not listed in List 1 and so on
throughout all the lists recorded for each site.Species richness is the species total/bird
species diversity reached when no new species
are recorded. Species richness is thus assumed
to be an approximate number of bird speciesdiversity present in a habitat at that time of the
year

SYSTEMATIC DATA COLLECTION
contd
Other data collected from site/habitat are:
locality, habitat type, location (geographic
coordinate), altitude, threats (ecological or
human induced: grazing, shifting
cultivation, evidence of poaching)
