Yes.Some byoncy force will act downward thereby increasing the weight.
Approved Tutor Answer15 Years agowhen bird is sitting on the floor of cage then the whole system is in rest....when bird starts flying then from conservation of momentam , cage should move in opposite direction hence we can say that it will exert a impulsive force to the hands of the person ....so therefore force exerted by the person should be more....
this problem can be compared to the case, when bullet is fired from a gun ,man exerts a force due to impulsive force developed after firing....
Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.

A car loaded with water having total mass 1000 kg moves on a straight horizontal Road starting from rest under the action of a force of 100 Newton. The water spills throw a small hole in the bottom at a rate of 0.1 KG per second the velocity of cart after 300 seconds is nearly.
