We describe the number counts and spatial distribution of 239 distant red galaxies ( DRGs), selected from the Early Data Release of the UKIDSS Ultra Deep Survey. The DRGs are identified by their very red infrared colours with (J - K)(AB) > 1.3, selected over 0.62 deg(2) to a 90 per cent completeness limit of K(AB) similar or equal to 20.7. This is the first time that a large sample of bright DRGs has been studied within a contiguous area, and we provide the first measurements of their number counts and clustering. The population shows strong angular clustering, intermediate between those of K-selected field galaxies and optical/infrared-selected extremely red galaxies. Adopting the redshift distributions determined from other recent studies, we infer a high correlation length of r(0) similar to 11 h(-1) Mpc. Such strong clustering could imply that our galaxies are hosted by very massive dark matter haloes, consistent with the progenitors of present-day L greater than or similar to L(*) elliptical galaxies.
