Video can not be uploaded. Photo ML27346321 shows 62 White-throated Needletails (already a high count) and that is only a small part of the sky, which was covered in Needletails at one point. Roughly counting in tens and rounded down gave the count of 120. I could not find a Silver-backed Needletail in any of the photos. There was a smaller flock of at least 5 Silver-backed Needletails earlier in the morning in about the same area.
