Investiopedia define the bird-in-hand principle as following:

Definition of 'Bird In Hand'

A theory that postulates that investors prefer dividends from a stock to potential capital gains because of the inherent uncertainty of the latter. Based on the adage that a bird in the hand is worth two in the bush, the bird-in-hand theory states that investors prefer the certainty of dividend payments to the possibility of substantially higher future capital gains.

Investopedia Says

Investopedia explains 'Bird In Hand'

The theory was developed by Myron Gordon and John Lintner as a counterpoint to the Modigliani-Miller dividend irrelevance theory, which maintains that investors are indifferent to whether their returns from holding a stock arise from dividends or capital gains. Under the bird-in-hand theory, stocks with high dividend payouts are sought by investors and consequently command a higher market price.

Read what Ken Kaufman (2011) writes about the topic "
Which brings me to the question I want to discuss in this post: Why does the saying “a bird in the hand is better than two in the bush” have to be so linear and definitive? Can’t we have both? Don’t we need to figure out how to have both if we want our businesses to survive?

I realize that one of the meanings of this saying is to help us be grateful for what we have, but entrepreneurs who spend too much time enjoying the fruits of their labors need to be careful. We are under constant attack by hungry, aggressive competitors who are frustrated they didn’t get the bird we got but are anxiously plotting to get the two in the bush."
