🪺 Barn Swallow Life Cycle in Rural Pakistan | From Nest to Chick (2023–2025) | BiodiversiGrapher® 🐦

🎥 Witness their mud-built homes, aerial acrobatics, and the journey from egg to fledgling — filmed by BiodiversiGrapher® 🗓 Observation Dates: • 27 May 2023 • 26, 27 March 2024 • 16, 31 March 2025 🎼🎓 Dr. Syed Aftab Hussain Shah 🎧🎤 🐦 Species Focus: Barn Swallow (Hirundo rustica) Barn Swallows are graceful aerial insectivores recognized by their forked tails and rusty throats. They migrate vast distances each year, breeding in open structures such as houses and barns. Their mud-built nests support multiple generations, with both parents sharing feeding duties. In this episode, BiodiversiGrapher® brings you intimate scenes: nest building, egg laying, and chick rearing — all filmed in the wilds of Pakistan. Watch the teamwork, dedication, and incredible adaptation of these birds in human-modified environments. 🚨 Note from the Field: An unfortunate incident was observed where a mother swallow tragically collided with a ceiling fan and died on the spot while defending the nest — a sobering reminder of the dangers these birds face while nesting alongside humans. 🌟 Narrative Highlight: Discover how nature thrives right next to us: • Building sturdy mud nests on walls and ledges 🏠 • Females laying eggs while males keep vigilant watch 👀🥚 • Chicks hatching and growing in semi-urban environments 🐥 ⏱ Timestamped On-Screen Descriptions: 00:00:00:00 – 00:00:02:11 Male Barn Swallow perching calmly on the bulb holder—territorial watch begins. 00:00:03:20 – 00:00:13:22 Female Barn Swallow incubating—likely on eggs. Male guards nearby, signaling pair coordination. 00:00:24:21 – 00:00:33:16 Female leaves nest with a distinct vocalization. Faint, low-pitched tones emerge from the nest, possibly chick sounds—though partially masked by ambient bird activity. 00:00:34:13 – 00:01:04:15 Both adults perch on the nest rim, uttering special calls or short songs. The female inspects the nest interior—behavior possibly linked to chick care or egg-checking. Due to non-invasive filming and limited gear, exact visuals inside the nest are unavailable. Both birds depart suddenly. 00:01:15:24 – 00:01:46:25 A similar session: Both male and female conduct a brief vocal interaction atop the nest. They depart soon after. A subtle vocalization is heard post-departure—likely from nestlings. These repeated patterns suggest "guarding sessions." 00:01:47:11 – 00:01:54:25 Female departs again. Low, faint calls are detected from within the nest—likely chick presence. 00:01:55:16 – 00:02:12:27 Male possibly guarding, intermittently giving short contact or watch calls. 00:02:13:22 – 00:04:36:23 Female remains inside the nest for a prolonged period. The male perches on a net cable. A potential key developmental moment—perhaps early chick care. 00:04:38:08 – 00:05:14:07 A breakthrough—first visual of a baby Barn Swallow! Possibly just one chick observed. 00:05:14:23 – 00:05:18:08 Thank you for watching.
