Original Title: AnÁlisis comparativo de cinco sistemas de muestreo del uso de espacio en aves forestales
Summary:
This paper deals with a comparative analysis of the 5 most common recording techniques for the use of space by forest birds. All recording methods give very similar results (average similarity for substrates and heights between all methods: 99.4 %) and show a similar stabilization degree. No constant trends have been found in relation with the different conspicuousness among resources due to the recording techniques. As a consequence, overlap results are very similar as well. Results of all resources follow a regular distribution, and are statistically independent when the time between 2 consecutive records is higher than 30 seconds. Taking into account these facts it seems advisable to take records at «first sight», or at 30 second intervals in order to obtain a higher number of records.
