Poila Baisakh Bird Count (PBBC)

Celebrating Nature and Citizen Science in Bengal

The Poila Baisakh Bird Count (PBBC) is a commendable initiative organized by the Birdwatchers’ Society to commemorate the Bengali New Year through the appreciation of nature and the practice of citizen science. This annual event, held in mid-April, invites bird enthusiasts from across the region to immerse themselves in the outdoors, keenly observing and meticulously documenting the avian diversity that graces urban parks, wetlands, and forests. By intertwining cultural celebrations with conservation efforts, the PBBC not only raises awareness about local bird species but also contributes invaluable data to global bird monitoring platforms such as eBird.

Relevance of PBBC

The timing of the Poila Baisakh Bird Count is particularly significant. April is a fascinating month for bird activity in West Bengal. During this period, many birds are actively singing and breeding. Concurrently, numerous other species are in the midst of their migratory journeys towards more northerly breeding grounds. Conducting a bird count during this critical juncture provides an opportunity to monitor the status of both breeding and migratory birds. Such data is instrumental in understanding the dynamics of bird populations and the challenges they face. By aligning the bird count with the ‘Poila Baisakh’ cultural festival, the PBBC underscores the deep-rooted relationship between people and the environment.

Monitoring Breeding and Migration

By documenting bird species and their behaviours during this period, participants contribute to a better understanding of the timing and patterns of breeding and migration. Over the years, these snapshots taken during the summer months can offer insights into the impacts of climate change on migration and breeding phenology. As climate change alters the natural world, having historical data becomes crucial in tracking shifts in bird behaviour and distribution.

Citizen Science and Data Contribution to Global Platforms

One of the core strengths of the PBBC is its emphasis on citizen science. By involving the community in bird monitoring efforts, the initiative fosters a sense of responsibility and connection to the natural world. Participants, regardless of their level of expertise, become active contributors to scientific knowledge. Their observations and recordings help build a comprehensive database that is accessible to researchers and conservationists worldwide. This democratization of science empowers individuals to make meaningful contributions to environmental conservation.
The data collected during the PBBC becomes part of a larger global effort to monitor bird populations. By contributing the observations to platforms like eBird, the PBBC participants play a vital role creating a comprehensive picture of avian diversity and trends.

Community Building

T PBBC fosters a sense of community among participants. It also serves as an educational exercise for the young participants apart from its scientific value. By instilling a love for nature and birdwatching at an early age, events like the PBBC nurtures a generation of environmentally conscious individuals.

Birdwatchers from diverse backgrounds come together, sharing their passion for birds and nature. This sense of camaraderie riding on the spirit of the festival strengthens the bonds within the community and creates a supportive network of conservation advocates. The PBBC is thereby a step towards enriching the collective understanding of Bengal’s avian diversity.

Note: Poila Baisakh” is a festival that celebrates the first day of the Bengali New Year, and marks the onset of summer.

Poila Baisakh Bird Count

poILA BAISHAkH BIRD Count (pBBC) 2024

Report by pampa mistri

Poila Boishakh, being the first day of the Bengali Calendar, is a big day in Bengal. Similarly, the Poila Boishakh Bird Count (PBBC) is literally a BIG DAY in the BIRDING calendar of West Bengal (WB). For the ‘bong birders’, this day seems to be emerging as a statewide competition to see who can spot, identify and record (on eBird) the greatest number of bird species on this day. In 2023, the year in which PBBC was launched, (https://birdwatcherssociety.org/featured_item/fantail-vol2_issue4/) we had 127 birders who documented 387 species from 19 districts in 2 days.

In 2024 the event was set for April 13-14 in collaboration with eBird India and Bird Count India. Both days at least 85 birdwatchers from West Bengal came together -103 birdwatchers were on field on Day 2 alone! 357 species were documented in 339 checklists from 19 districts! This year we missed out on counts from Coochbehar, Murshidabad and Uttar (North) Dinajpur districts of WB.

Birds and their population numbers are essential for indicating the overall health of ecosystems. The changing climate has affected bird migration due to alterations in bird habitats. Counting or monitoring is central to ecological studies and conservation research in ornithology. Monitoring helps to establish a baseline for natural variability in species abundance and distribution. This eventually becomes an essential tool for identifying changes that indicate a population abnormality trend. This can act as an early warning system to initiate conservation measures to help prevent further deviations and ultimately help support biodiversity.

April in WB is a crucial time in the avian calendar as it marks spring’s onset. But with the changing climate, April now marks a shortened spring and the beginning of summer. The Poila Boishakh Bird Count (PBBC) across the state at this pivotal juncture is an essential bio-indicator of breeding birds and migrants. Over time, these snapshots during summer can indicate the impacts of climate change on migration and breeding phenology. It may be a good idea to publicise this event at the highest level and institute a recognition of the effort.

Among the species reported were the following which were classed as High Priority in the SoIB 2023 report: Little Ringed Plover, Kentish Plover, Spotted Redshank, Little Stint, Rufous-necked Hornbill, Bristled Grassbird, Blue-capped Rock-Thrush, Thick-billed Flowerpecker, Olive-backed Pipit, Pied Avocet.

Among the participants, Saikot Das, Bahruddin Sk. and Anish Bera were the top contributors.

Poila Baisakh Bird Count (PBBC) 

15-16 April 2023 

Different sates in India have connected their bird monitoring program with their festivals so that amongst the festive mood, more and more people get involved in bird watching, which eventually will help to aware people about the biodiversity of their surroundings. E.g., Bihu Bird Count, Onam Bird Count, Pongal Bird Count. Even Nagaland had their 1st bird count program named Tokhü Emong Bird. Only we didn’t have any such events connected with our festivals, especially with summer festivals. At the same time, April is an interesting time for birds in WB when many are already singing and breeding, particularly in the Western and Northern hills – but many others are still moving through towards more northerly breeding grounds. A count during this crucial period across the state can help monitor the status of breeding birds as well as the status of migrants moving through. Over time, these snapshots during summer can inform us about impacts of climate change on migration and breeding phenology.

 So, 2023 April 15-16 during Bengali New Year (Poila Baishakh, we at BWS, started our first ever annual summer bird count program – PBBC (Poila Baishakh Bird Count) in West Bengal in collaboration with eBird India and Birdcount India.

For those who don’t know what “Poila Baishakh” in Bengal is:

“Poila Baisakh” is a festival that celebrates the first day of the Bengali New Year, and marks the onset of summer.
