1 Normally flickers lay 6 or 7 eggs.  Cowbirds (which parasitize the nests of other birds) usually lay about six eggs (one each day) in different nests, wait a few days, and then start again. They may lay more than 11-20 eggs per season. A captive female was recording laying 77 eggs, 67 of those in a continuous sequence.
What is nystagmus? Nystagmus is an involuntary condition in which the eyes make rapid, repeated, uncontrolled movements. These eye movements may be in any direction including horizontally, vertically, or rotationally (in a circle). Many people with nystagmus do not experience visual symptoms.
Most people with nystagmus have reduced vision. Nystagmus is a sign of a problem with the visual system or the pathways that connect the eyes to the parts of the brain that analyse vision. These parts of the brain deal with eye movement. It is not really a condition in its own right.ost people with nystagmus have reduced vision.
