We present the results of an HK ^ { \prime } wide-field survey encompassing the Hubble Deep Field and its Flanking Fields .
Our wide-field survey provides uniform coverage of an area 61.8 arcmin ^ { 2 } to a depth equivalent to K = 20.1 at 5 \sigma .
We have also imaged the Hubble Deep Field in HK ^ { \prime } , providing uniform coverage of an area 7.8 arcmin ^ { 2 } to a depth equivalent to K = 21.2 at 5 \sigma .
Using these data in combination with new deep UH 8K V and I imaging obtained on the CFHT , we find only a small population of objects with colors redder than an equivalent I - K = 4 , the color expected for an evolved elliptical at z > 1 .
We infer that only a fraction of the local field elliptical population with M _ { K } < -23.4 could have formed in single bursts at high redshift .
