juvenile gull id please (1 Viewer)

IMHO Photo is too indistinct to nail it to one or the other on this one.

Some possible tips for future, in flight juv Herring would show pale inner primaries. Also would have dark tertials distinctly notched with buffy white, and a more brownish-grey cast to its plumage, with emphasis on the brown. A juv LBB would have all dark primaries, with fine pale tips to all dark tertials. Its overall plumage more greyish-brown, with more emphasis on the grey-black.

It´s a very young juvenile with not fully grown primaries. The seemingly uniform dark greater coverts is a LBBG feature over HG wich have pale greater coverts with dark banding, or if you like, with even dark and pale barring.
And as noted by Phil, the all dark inner primaries and darker plumage are good features from HG which has obvious paler inner primaries ('window') and paler plumage.
