It is a drop compared with 2017 when 1,314 stork couples were recorded.In 1934, there were 2,219 couples nesting in Slovakia but only 1,018 white stork couples nested
in Slovakia back in 1984.This was caused not only by a lack of food and suitable nesting spots in Slovakia over the years but also by the fact that not all white storks make it to Africa and die on their way there.

For normally distributed variables (one-sample Kolmogorov-Smirnov Z test, P>0.05), independent-samples T-tests were used to identify significant differences between sites with successful nests
and ones with unsuccessful nests
Asian hornet nests
are generally spherical in shape and light brown in colour, and in daylight hours will be busy with Asian hornets flying to and from the nest

House wrens will build their nests

We included killdeer nests
in our study that were discovered incidentally or located through area searches of select oil pads and heavily grazed patches within pastures, 2015 and 2017.
We collected nest
concealment data only in 1998, 2001, and 2004, and these data could not be obtained for all nests
from all perspectives of a nest
(see below); therefore, we did not include nest
concealment as a covariate in our Program MARK analyses.
Between 1904 and 2013, only 13 nests
were found in northern Alaska; nine nests
