  We present optical and near-infrared searches for afterglow emission from the
first four Swift bursts with accurate positions from the X-ray Telescope (XRT).
Using telescopes at Las Campanas, Keck, and Palomar observatories we rapidly
identified and followed up afterglows for three of the four bursts. The burst
positions were also observed with the Very Large Array, but no radio afterglow
emission was detected. The optical/NIR afterglows are fainter than about 75% of
all afterglows detected to date, with GRB 050126 being the faintest, and were
identified thanks to accurate and rapid positions from the XRT and rapid
response with >1-m telescopes. This suggests that the fraction of dust-obscured
bursts is small, <10% when combined with afterglows localized by the HETE-2
Soft X-ray Camera. The X-ray fluxes are typical of the known population, with
the exception of GRB 050126 which has the faintest X-ray afterglow to date
(normalized to t=10 hr), and was detected thanks to a response time of only 130
s after the burst. Finally, we find that all three optical/NIR afterglows are
located <2 arcsec away from the nominal XRT positions, suggesting that the XRT
is capable of delivering highly accurate positions, which will revolutionize
afterglow studies.
