Sliding type birdcage facilitating observation of bird behaviors

The invention relates to the technical field of birdcages, in particular to a sliding birdcage facilitating observation of bird behaviors. Comprising a bottom plate and a top plate body, the bottom plate and the top plate body are in sliding connection with protection mechanisms correspondingly, the upper protection mechanism and the lower protection mechanism are in sliding connection, and a plurality of stretching mechanisms are arranged on the outer sides of the upper protection mechanism and the lower protection mechanism; the ejection ring in threaded connection with the lead screw moves upwards, so that the inclined ejection rod is pushed to expand the arc-shaped ejection plate outwards, a plurality of upper and lower auxiliary vertical plates on the outer side of the arc-shaped ejection plate move outwards, the protective curtain is released, the moving space of birds on the inner side of the protective curtain is enlarged, and the behaviors of the birds can be observed conveniently. Meanwhile, the eje
