I consider your domain mid hundreds, other domains with "bird" have done good (luckybird.com fetched $2,472, frenzybird.com fetched $1,088, bettybird.com fetched $695, lillybird.com fetched $1,095...lazybird.com fetched $688)
A counter of $1k may be a little much, try $500 - $600 (depending on his willingness)
