觀察細節
Initially found one Swallow/Martin with a light belly and dark upperparts flying around one of the viewpoints with the Dusky crag Martins and assumed Red-rumped swallow, since there were a flock of Red-rumped swallows flying at a lower level around the hill and we couldn't get good enough views with binocs. Took a few images and after reviewing them, bird certainly does not fit the giss of a Red-rumped swallow, with a shallower forked tail, whitish undertail and clean white underparts. Edit: Took a few opinions and all are in favour of Common House-Martin from the deeper forked tail. Updated
