Kavanau (1987) was the first to find that unique bi-parental care seen in modern birds probably evolved from extinct birds. They developed the ability to provide protection, escorting, nurturing and egg guarding abilities for their young.

In birds, this parental care system is generally attributed to the ability of male birds to engage in most parental behaviours, with the exception of egg-laying. Due to their endothermy and small size at birth, there is a huge pressure for infant birds to grow up quickly to prevent energy loss.
Birds also prefer structures that blend into the environment, so if the nest box is painted, earth tones (grey, green, brown) are your best bet. In short, if attracting birds is your primary goal ...

About 30% of the 500 known fish families show some form of parental care, and most often (78% of the time) care is provided by only one parent (usually the male). Male care (50%) is much more common than female care (30%) with biparental care accounting for about 20%, although a more recent comparative analysis suggests that male care may be ...
