> # Search for observation fields and values
> 
> You can specify observation fields and their values in the URL. For example, here are all of the observations with the observation field “Roadkill” set to “Yes”.
> 
> [https://www.inaturalist.org/observations?field:roadkill=yes](https://www.inaturalist.org/observations?field:roadkill=yes)
> 
> You can search for all observations with a field regardless of the field value (e.g. the field “[Habitat (s Afr)](https://www.inaturalist.org/observations?field:Habitat%20(s%20Afr)&place_id=any)” only):  
> `&field:Habitat%20(s%20Afr)`
> 
> or with a field and value (e.g. “[Habitat (s Afr)=Nama Karoo](https://www.inaturalist.org/observations?field:Habitat%20(s%20Afr)=Nama%20Karoo&place_id=any)”):  
> `&field:Habitat%20(s%20Afr)=Nama%20Karoo`
> 
> You can also find observations missing a named field:  
> `&without_field=Name of Associated Plant`
> 
> You can easily combine these with other search strings. For example, the following shows all observations marked as being of insect herbivores of _Eucalyptus_.
> 
> [https://www.inaturalist.org/observations?taxon\_id=47158&field:Interaction-\>Herbivore%20of=51815](https://www.inaturalist.org/observations?taxon_id=47158&field:Interaction-%3EHerbivore%20of=51815)
> 
> The taxon ID for Insecta is 47158 and for _Eucalyptus_ is 51815 (which you find from the URLs of their taxon pages, [https://www.inaturalist.org/taxa/47158-Insecta](https://www.inaturalist.org/taxa/47158-Insecta) and [https://www.inaturalist.org/taxa/51815-Eucalyptus](https://www.inaturalist.org/taxa/51815-Eucalyptus)). The observation field used here is “[Interaction-\>Herbivore of](https://www.inaturalist.org/observation_fields/3136)”. Note that the space in that field name needs to be [replaced with a %20](https://www.urlencoder.org/) in the URL so the browser doesn’t get confused.

> **Observation field view**  
> [https://www.inaturalist.org/observation\_fields/1234](https://www.inaturalist.org/observation_fields/1234)  
> Observation field view for a value: (e.g. Fynbos in Habitats-s-afr):  
> [https://www.inaturalist.org/observation\_fields/7498?value=Fynbos](https://www.inaturalist.org/observation_fields/7498?value=Fynbos) (case sensitive)  
> Ascending list of observation fields:  
> [https://www.inaturalist.org/observation\_fields?order\_by=name&order=asc](https://www.inaturalist.org/observation_fields?order_by=name&order=asc)  
> Descending list:
