As I reflect on my journey in ornithology and natural history, I should share the profound impact that Dr. Salim Ali, the Birdman of India, had on my life. It was a remarkable privilege to work under his guidance as his last student, a privilege I cherish deeply.

I first came to know Dr. Ali through my Dhaka University teacher, Dr. Ali Reza Khan, who was his first Bangladeshi student. In 1982, at the age of 86, Dr. Ali, at the recommendation of Dr Khan, agreed to accept me as his PhD student, a gesture that marked the beginning of an incredible mentorship. His initial letter to me, while somewhat hesitant, showed his willingness to support my project proposal on a comparative study of laughing thrushes in the Himalayas and the hill of the Western Ghats in southern India. I remember feeling both honored and intimidated by the opportunity.

Dr. Ali was not just a mentor; he was a hands-on supervisor, eagerly awaiting my field reports every month. He made it a point to visit my field stations, bringing with him a big basket of mangoes, which added a personal touch to our professional relationship. I can still recall the day I accompanied him to Kalona, near Nainital in the Himalayas, in March 1983, when I was able to study four species of laughing thrushes. As we trekked through the hills, his passion for nature was palpable, extending beyond birds to include butterflies, wildflowers, berries, and the serene landscapes around us.

Despite his age, Dr. Ali was vibrant and engaged. I remember how he would call me at 5 am from his stay at the Royal Bombay Yacht Club to discuss my studies. I often arrived on time, but he was always already at work, driven by his insatiable curiosity and dedication. These early morning discussions were a blend of learning and laughter, often punctuated by his love for cold coffee and the mangoes he generously shared.

One of the qualities I admired most about Dr. Ali was his humility. He accepted new ideas gracefully, even when they challenged his long-held beliefs. During our fieldwork, I discovered that the laughing thrushes in southern Indian hills often lived in pairs, contrary to his assumption that they were gregarious. When I presented my findings, he visited my study areas, evaluated the evidence, and, once convinced, embraced my conclusions without hesitation.

Dr. Ali's commitment to bird conservation extended beyond research. He believed deeply in the ecological importance of birds, arguing compellingly that their role in controlling insect populations was vital for sustaining plant life and, ultimately, all animal life, including humans. His passion for conservation resonated with influential figures like Jawaharlal Nehru and Indira Gandhi, who recognized his dedication to preserving India's natural heritage.

Throughout our time together, Dr. Ali shared not just his knowledge, but also his life experiences. He often spoke fondly of his wife, Tehmina, who played an essential role in his success. I remember him reflecting on how she adapted to life in the forests, supporting him tirelessly during challenging times. This tribute to his partner underscored the importance of support and companionship in achieving one's goals.

Dr. Ali's sense of humor was another cherished aspect of our interactions. On his 86th birthday, surrounded by friends in Borivali National Park, later re-named Sanjay Gandhi National Park, in Bombay, he playfully requested extra candles on his cake, ensuring that no one would doubt his age. His laughter was contagious, and his anecdotes often left us in stitches, even when he was addressing serious topics.

Sadly, I last saw Dr. Ali in 1986, just before he fell ill. His final letter to me expressed his uncertainty about attending an award ceremony in the Asiatic Society in Dhaka, a poignant reminder of his declining health. When he passed away on June 20, 1987, it felt like the world had lost a guiding star. I visited his grave in 1988, still grappling with the reality of his absence.

Dr. Salim Ali was more than a teacher to me; he was a mentor, a friend, and a source of inspiration. His legacy continues to drive my work and passion for natural history. November 12 was his 128th birthday, when all his students, colleagues, and friends paid tribute to this revered naturalist. His love for nature and dedication to conservation live on in us, and I will forever be grateful for the profound influence he had on my life.
