This photograph is part of a series titled "Mothers in Tangent". I was fortunate to chance upon this female Long-tailed Macaque cradling her infant at the summit of Bukit Timah Hill, the highest natural point in Singapore. Coincidentally, a human mother is captured in the background tending to her daughter's hair—a fleeting moment where she mirrors the macaque, highlighting the universality of parental instincts. These two worlds exist in tangent, both nurturing their offspring as they reach the peak.
