Beamer bibliography: too much space between title and content

Question

I am adding the bibliography in the Beamer, and there is too much space between the 'References' and the content. How can I shrink the space in between for all several pages of references? Many thanks in advance!

\begin{frame}[noframenumbering,plain,allowframebreaks]\frametitle{References}
     \printbibliography 
\end{frame}

Answer 1

You can add t to the frame.

\documentclass{beamer}
\usepackage{biblatex}
\addbibresource{biblatex-examples.bib}
\begin{document}
\begin{frame}
\cite{angenendt}\cite{augustine}
\end{frame}
\begin{frame}[noframenumbering,plain,allowframebreaks]
\frametitle{References}
\printbibliography
\end{frame}
\begin{frame}[noframenumbering,plain,allowframebreaks,t]
\frametitle{References}
\printbibliography
\end{frame}
\end{document}
