Delete Nodes of Values smaller than 1000 in stacked bar chart

Question

I would like to delete the labels of all the values, which are smaller than 1000, because they can't be seen correctly.

I searched for a long time and I think there were some similar questions, but unfortunately my coding skills are not the best and that's why it wasn't really working for me. I hope someone can help me. Thanks in advance!

Here is my code:

\begin{tikzpicture}
\begin{axis}[  
compat=newest,   
ybar stacked,     
bar width=40pt,     
%     
nodes near coords,
every node near coord/.style={/pgf/number format/fixed,font=\tiny},
point meta=rawy,    
legend style={at={(0.5,-0.15)},       
anchor=north,legend columns=-1},
%     
axis x line=bottom,     
axis y line=left,
ymajorgrids=true,     
grid style=dashed,
%     
ylabel=Anzahl,     
ymin=0,     
scaled ticks=false,
tick label style={/pgf/number format/fixed},
enlargelimits=auto, 
enlarge x limits=0.3,   
%          
symbolic x coords ={<1980,1980 - 2021,2021},     
xtick=data,  
/pgf/number format/.cd,        
use comma,         
1000 sep={.}
]
\addplot[fill=Blau] coordinates {
(<1980,8653)       
(1980 - 2021,17786)
(2021,26439)  
};   
\addplot[fill=BlauHell] coordinates {
(<1980,501)       
(1980 - 2021,2622)
(2021,3123)       
};  
\addplot[fill=BlauMittel] coordinates {
(<1980,271)       
(1980 - 2021,2601)
(2021,2872)      
};  
\addplot[fill=HellGrau] coordinates {
(<1980,503)       
(1980 - 2021,3694)
(2021,4198)      
};  
\addplot[fill=Gruen] plot coordinates {
(<1980,488)       
(1980 - 2021,2474)
(2021,2961)     
};  
\legend{R1,R2, R3, R4, R5}
\end{axis}  
\end{tikzpicture}
