Llevo un tiempo usando la app NestWatch y la verdad es que me ha parecido muy práctica y fácil de usar. Te permite registrar datos sobre nidos —especie, huevos, polluelos, fechas— y todo se guarda en una base científica que apoya la conservación de aves en el mundo. Funciona sin internet, sincroniza con la versión web y es ideal si manejas cajas nido o simplemente quieres llevar un seguimiento responsable de lo que observas. Me gusta mucho porque además de aportar a la ciencia, aprendes un montón sobre el comportamiento de las aves. Si te interesa la naturaleza y la observación de aves, esta app realmente vale la pena.

I absolutely love using the nest watch app! It’s intuitive and well designed so that it makes it easy to track nesting birds anywhere I go. Logging data is straightforward and detailed. You can log everything from nest materials to the number of eggs and hatchlings, which makes the observations really meaningful and accurate. Another thing I love is the ability to upload photos. It’s super cool to look back and see the progress of birds as they grow up. I’ve learned a lot about local species and their nesting behaviors through the app. Highly recommend to anyone who enjoys birding and wants to contribute to real scientific research. The Cornell Lab of Ornithology has done a great job with making an app that’s super fun and easy to use!

Wonderful idea for an app but it’s basically unusable. The app constantly glitches and crashes. I can’t even load previous nest data or enter new data while in the field despite having good service. Had the same problem last year and it’s still not fixed.

I had been using this app (iPhone 11) successfully with a large number of nests but then had to reinstall the app and now it is regularly not loading points in the map, not letting me select nests from the map, and just crashing unexpectedly. I am hoping updates are coming?

I realize this app probably doesn’t get a lot of funding so am making these comments knowing it probably won’t change, but here are my wishes for the app: Add Touch ID so I don’t have to put in credentials every time, or at least let me save my ID/pw Add “select from photos” to the photo page so I don’t have to go to the visit to add it

I was excited to download this app but when I agreed to the rules of nest watching I needed to restart the whole signing up.😡

Well this App was a bit clunky it was working. It starts by saying it’s syncing offline data, which I didn’t enter, the there’s a continue button. Nothing happens when you tap it. Both my iPhone and the app are running most recent versions.

Been using the app for several years and have seen continuing improvements in the user interface but performance makes it unusable.

It’s nice that we can all participate in citizen science from our smartphone, but it’s obvious this is an app from a non-profit with limited funds. The app often freezes. Talk-text and auto-correct are both turned off inside the app, so you must very carefully type out all notes and make your own corrections. You cannot upload photos while making an initial entry; you can only take real-time photos. If you try to do so, you end up loitering at the nest violating the contract you agreed to and freaking out the mom & nestlings while you stand at the nest frantically trying to accurately make your entries & get to the one-and-only screen to take your real-time photo. You can only upload pics by returning to the entry after it is saved. You should be able to upload a photo when making the initial entry. It takes numerous seconds to upload each photo. If you exit the app before it finishes uploading, there will be a perpetual message every time you open the app telling you there is an upload pending, but when you access that error message, it tells you there are none pending. The message remains until you find the hidden photo that never finished uploading, delete it, and re-upload it. The web client and the app often seem out of sync. I enjoy NestWatch, feel like I am contributing to ornithology, and recommend the app to others... but I often cuss out my phone while using it! 🤬
