No it doesnt.It is usually a warning.
I suppose you could interpret it that way, since a bird tapping on a window is an omen of death.
A bird tapping on a window can indicate that it sees its reflection and mistakes it for a rival bird, leading to territorial behavior. It may also be trying to get your attention for food, water, or shelter. If the behavior persists, consider covering the window temporarily to prevent further stress on the bird.
The word 'tapping' is a special case. It in its various forms can be used as both a verb or onomatopoeia.If you were to say, "The bird was tapping at the window.", it would be categorized as a verb.On the other hand, if you were to say: "There, once again, appeared the bird at the window. Tap! Tap! Tap!, I heard on the glass."The 'tapping' would be onomatopoeia.
the tapping is called "MORSE CODE"
knocking
The speaker suggests that the tapping sound might be caused by someone tapping on the window to try and scare them or get their attention.
Maybe it wants to come into your house? Hungry? Water? Give it some food. Maybe a bit coocoo in the head????

It could mean that the bird sees its reflection in the window and thinks that it is seeing another bird, or it could mean that, at some time, someone put out bird seed onto your window sill.
