Kine Weekly wrote: "Eichberg's production is very efficient in technical effects, but his plot is full of loose ends. The mystery is so full of 'red herring' trails that one is apt to lose interest in the characters. The dialogue is not a strong point. One feels that had it been better, the plot would have gained some conviction and force."
Film Weekly wrote: "Despite the fact that the acute fim-goer will probably spot the culprit early in the film, there are plenty of thrills to entertain you in this British picture, which moves faster than most of its type. Jack Raine, Jameson Thomas and the small-part players give good performances, but the feminine members of the cast are not so effective."
The Daily Film Renter wrote: "Jack Raine, scarcely the physical type for the detective role, acts it in an effective comedy vein nevertheless. Jameson Thomas is as good as ever as the mysterious Lake, Muriel Angelus adequate as the vamp, and Eve Gray has only to look pretty. Franklyn Bellamy has an effective heavy part and a really excellent piece of comedy is put over by Margaret Yarde as a police spy. Despite a certain number of dramatic loose ends,
Night Birds will provide exciting fare for popular audiences." ==References==
