Common Bird Monitoring Programme

Next count

14 to 21 January 2018, organised by BNHS

Bombay Natural History Society (BNHS) has announced its bird count for the winter season from 14 to 21 January 2018 under its Common Bird Monitoring Programme. BNHS invites bird watchers, NGOs, ornithologists, and nature lovers to participate. The counts will be conducted across three seasons on a pan-India level. This programme is completely based on scientific methodology, the data which will be generated with the help of Line Transect methods, will be useful for conservation of our neighbourhood species.

Kindly choose the preferable date in the given week and contribute your valuable time to count our common birds.

About Common Bird Monitoring Programme

Common Bird Monitoring Programme is a citizen science programme. The objective is to involve more and more people in observing birds in their own backyard or a location they visit regularly. There are several existing good initiatives where people can record their bird sightings. However, there is a need to accurately monitor trends in common bird populations. Hence, we have started this unique activity in India namely Common Bird Monitoring Programme (CBMP).

Objectives of CBMP

  • To provide information on year-to-year and longer-term changes in population levels for a wide range of birds across a variety of habitats throughout India.
  • To understand the extent to which bird populations are increasing or decreasing. Monitoring birds is crucial as they act as indicators of a region’s/habitat’s health.
  • To promote a greater understanding of the population biology of birds and, in particular, to focus on factors responsible for the declines.
  • To function as a key component of BirdLife’s monitoring strategy.
  • To promote bird conservation through the involvement of a large number of volunteer observers in survey work.
  • To observe and report the birds using a scientific methodology so as to get more authentic data.
  • To collect the data,ideally three times a year, so that in the long run we can get information about the changes in common bird populations.

Why we count Common Birds?

 Common birds are in trouble owing to urbanisation, industrialisation and other anthropogenic activities. For example, the population of House Sparrows is considered to be declining in the cities. Anthropogenic pressures in the form of concretisation and other developmental activities disturb many bird species living in an area. To know their current status, it is necessary to monitor these common species.

How to participate this programme (monitoring)

 We have plotted grids on the map of India with the help of GIS software. We need your location details (Google earth coordinates), and based on this, we shall send you a grid (which is in close proximity to your location). If performing the Line-transect in the selected grid is not possible due to geographical limitations/obstructions please write about it to us and we will send a new grid. Each grid is 2*2 km, and each participant will be sent a grid, in which they must perform the survey.

How to send us your location details (Google earth place mark)

DiagramNote

  • Those who have already selected the grid, they can perform line transect method on the same grid.
  • It is very important not to reject sites that may appear uninteresting. Grids containing a few species are just as valuable as the ones with many species.

Methodology

Line Transect Method

This method is practical and efficient. Line transect method is based on the theory of walking along a predetermined route at a fixed pace (speed) to record the birds on or near the line. With the help of these methods, you can observe the birds and note down the observations in the provided data sheet format.

When to visit

This winter the survey should be conducted   visit between 14 to 21  January 2018 (choose one day).Counts should ideally start around 7a.m. and no later than 9a.m (2hours). Counts will be more productive early in the morning; birds generally grow quiet and inactive during the middle of the day.

Weather

Surveys must not be carried out in conditions of heavy rain, poor visibility or strong wind. Birds generally become inactive in windy and wet conditions.Please record weather conditions in the boxes provided on the forms that describe cloud cover, rain, wind speed, and visibility. Choose one number (1-3) from each of the four headings below and enter these in the box provided. If the weather conditions change during your survey visit, please select a single weather category that best represents the overall conditions.

Tip for Birdwatcher

1) The transect is divided into 200m sections for convenience; please do not worry about birds at the boundary of two sections: record them in the one of the grid that seems more appropriate, but not in both. Try not to record the same individual bird twice, e.g. a bird that can be heard singing from several 200m sections should be recorded once, where itwas first detected.

2) Counts should ideally start around 7am, and no later than 9am.

3) Please try to keep the starting times similar within and across years. Please also try to keep visit dates similar across the years. Counts will be more productive in the morning, with birds generally becoming quiet and inactive during the middle of the day.

4) Do not record birds you see or hear before or after your transect line (i.e. behind your first 200m section or in front of your last 200m section).

5) Record all birds to the sides of your transect line.

6) Record all birds from your transect line that you can see or hear that are to the sides of your transect line, even if they are distant.

7) Ensure that only the number of birds recorded is written in each box on the count summary forms. Additional information such as ‘+’ or ‘many’ complicates the forms and should be avoided.

8) The previous data sheet has been updated so please kindly download the new datasheet attached and use that during the count.

9) Bird species names are recorded on the Field Recording Sheet in the order in which you observe them.

10) From your chosen starting point walk the transect route at a slow and methodical pace,pausing briefly to listen for bird songs and scan for birds flying overhead. Please note the starting and finishing times of each transect (using a 24-hour clock, e.g. 0730 for 7:30am, 1300 for 1pm).

11) As a guide, an average visit should last around 2 hours. Record all the birds you see and hear on the Data Sheet in the appropriate transect sections 1-10.

12) Space is provided on the recording form to allow you to tally different individuals of each species seen for each transect section.

13) Please complete the summary sheets (one for each transects) as soon as possible after each field visit and preferably on the same day. The form summaries the information sothat it can be analyzed. The Count Summary Sheet includes the names of species that aremost commonly encountered in most habitats in India.

14) If you record any species that are not on the list, please add the names of each additional species to the end of the list

15) At the end of the count summary sheet is a section where you may use your more general local knowledge of the site and/or area to provide information on any potential threats(both current or future) to the habitat and/or birds around your transect. This simple, butessential information will allow us to assess how the site is doing, what problems (if any)affect it and what is, or can be done to tackle the problems. If you are able and wish toprovide additional information, please contact at the given address.

Count Summary Sheets

It is pre-prepared excel sheet containing a comprehensive list of bird species commonly encountered in and around your location. The data collected in the field and noted on the data sheet must be entered onto the count summary excel sheet and sent to us (do not edit the data sheet; you have to just enter the number). If you have recorded a species which is not present in given excel sheet then you have to add the species name at the bottom of list. All the species names are arranged alphabetical order which is easy to search the species.

Submission of data

Participants can either submit their field data sheets to their project officer after every count or can enter the data onto the count summary excel sheet and send it via email (n.dudhe@bnhs.org).Once we have received your completed, filled data sheets for all three seasons (monsoon, winter and summer), you will receive an acknowledgement letter from the Bombay Natural History Society.

Note:-

  • You have to fill the given excel sheet (do not edit any species name, new species name add at the bottom of the list), you have to just add the individual number of species.
  • The data has to be mailed back to us in the given format i.e. excel sheet.( n.dudhe@bnhs.org)
  • Avoid sending word file, photograph of checklist.
  • The data should reach back to us within a month after the survey.
  • If you are not sure about the species but at least know the basic type of the bird then enter the data as (* species) (For e.g.: if you are not sure about which species of bulbul you saw: record it in bulbul species column)
  • Please specify the number of individuals you encountered in each grid during the survey. Do not use (ü) tick or any other symbol to record the sighting.
  • Please fill all the details required about the survey such as (Name of observer/(s), Area, District, state, Grid no., Habitat, time required, Date, etc.).
  • During conducting the survey make safety your first priority use personal protective equipment’s.
