Green Peas (GPs) and blueberry galaxies (BBs) are thought to be local analogs (z < 0.1) of high redshift Lyα emitters. H I study of these can help us understand the star formation in the primordial Universe. In this Letter, we present the results of H I 21 cm study of 28 high specific star formation rate (sSFR ≳ 10^–8yr ^–1) BBs at z ≲ 0.05 with the Five-hundred-meter Aperture Spherical radio Telescope. We report significant H I detection towards two BBs, namely J1026+0426 and J1132+0809, and discuss possible H I contribution from neighboring galaxies. The median 3σ upper limit of ∼2.0 × 10⁸M_⊙ was obtained on H I mass for galaxies with nondetections. We find BBs tend to have lower H I-to-stellar-mass ratio or gas fraction (f_H i_) than expected from f_H i_-sSFR and f_H i_-M_* relations for main-sequence galaxies. The BBs also have a median 3σ upper limit on H I gas depletion timescale (τ_H i_) ∼ 0.5 Gyr, about 1 order of magnitude lower than τ_H i_ for local main-sequence galaxies. We find a significantly low H I detection rate of 2/28 (7.1${}_{-4.6}^{+9.4}$%) towards these galaxies, which is similar to previous H I studies of low redshift GPs of high ionization parameter indicator, O32 ≡ O[III]λ5007/O[II]λ3727 ratios ≳10.
