  Recent results on the incidence of red galaxies in a > 100 square arcminute
field galaxy survey to K=20 and a K=22 survey of the Hubble Deep Field are
presented. We argue that a simple photometric redshift indicator, based on J-K
color and supported by spectroscopic results obtained with Keck, gives a
reliable lower limit of ~25% for the fraction of z>1 galaxies in the 100 square
arcminute survey. This fraction is substantially higher than found in previous
smaller samples, and is at least as consistent with predictions for pure
luminosity evolution as with those for hierarchical models. The same technique
yields a very low fraction for the HDF, which appears to be unusually
underabundant in red galaxies.
