@article{

The first line has mistakes. But I type them following a tutorial. What's the mistake?

Many thanks in advance!

How do you know that there is a mistake? Which error message do you get?

\begin{filecontents}{\jobname.bib}
    @article{

    	Author = {Bird, R. B. and Smith, E. A. and Bird, D. W.},
    	Title = {The hunting handicap: costly signaling in human foraging strategies},
    	Journal = {Behavioral Ecology and Sociobiology},
    	Volume = {50},
    	Pages = {9-19},
    	Year = {2001} }
\end{filecontents}
\documentclass{article}
\usepackage[backend=biber]{biblatex}
\addbibresource{\jobname.bib}
\begin{document}
I doubt that there is any useful information here~\cite{Birdetal2001}.
\printbibliography
\end{document}

It works perfectly fine.
